Saltwater Swimming Pools

Saltwater pools are a cheaper alternative to the traditional chlorine home pool because they do not require as many pool treatment chemicals. These pools are not as salty as seawater and have the same salt content as the human body. Ask questions here about installation, costs and upkeep here.

How much should a 25 x 45 inground pool poured concrete no decking two lights auto cover polaris cleaner and pool heater cost?

My suggestion is to Internet research styles. I kinda knew what I was looking for when I walked in, then they suggested some of the extras like the coping around the pool edging where it meets the concrete. Normally there's a metal part that the concrete meets to, the cantilever coping added a nice finish too it.

What are the advantages and disadvantages of a saltwater swimming pool?

You can go for copper ionization technology. It is one the best and healthiest alternative for saltwater swimming pool.

How do you convert your in-ground pool from chlorinated to saltwater?

Make sure your water is balanced and add salt (sodium chloride). You need to purchase a saltwater chlorine generator and you'll need to calculate the amount of salt you need. You would need to bring your pool salt content up to 3,000 ppm.

Concentration is the amount (by weight) of salt in water and can be expressed in parts per million (ppm). Here are the classes of water:

* Fresh water - less than 1,000 ppm

* Slightly saline water - From 1,000 ppm to 3,000 ppm

* Moderately saline water - From 3,000 ppm to 10,000 ppm

* Highly saline water - From 10,000 ppm to 35,000 ppm

Ocean water has a salinity that is approximately 35,000 ppm.

There is now a system with a healthier salt available Magnesium and Potassium Chloride. it is more expensive but in my opinion it is also much better and halthier than Sodium chloride. The aticle I am using is from poolrite

How many gallons of water are in a 24 foot round pool that is 4 feet deep?

For a round above ground pool, the calculation is:

Diameter x Diameter x Depth X 5.9 = Number of Gallons

Please note that the depth is the ACTUAL water depth NOT the height of the pool wall (the water is usually around 6 inchs lower than the wall height).

For your example:

For a 24-foot round pool with a actual water depth of 3.5 ft: 24x24x3.5x5.9 = 11,894 or around 12,000 gallons.

Are saltwater pools cheaper or better?

Salt water pools produce "chlorine," so it is cheaper. It is also more troublesome. Yugos were also cheaper ... you get what you pay for.

If your chlorine generator is working properly and your salt levels are correct it will work just fine.

Though I have never been in a saltwater pool, my children have swam in several. They swear by it and insisted that ours be saltwater. I trusted their there request and went ahead to pay the extra money for something I know nothing about.

"Are saltwater pools cheaper or Better"? Really its not a Salt water Pool, bottom line is your gonna have saltwater in your pool with any type of sanitizer.Boxed chlorines are produced with sodium.

I like the easy part of the salt generator, less work and worry. Nothing beats a clean clear pool, I have been using generators for over 20 years, today's versions are light years ahead of my first unit in terms of cost and performance, you really get alot with today's modern generators at one huge value.

A chlorine generator is easy, efficient and cost effective. Of course there are cheaper ways to sanitize your pool. Most owners find they like the increased softness from a little salt in the water and it's easier to maintain a clean pool. When your not home it's especially easy and if you happen to go on vacation for a week or two.Your pool professional can recommend and professionally install the right unit for your pool.That also reminds me I know someone who doesn't have a heater for their in-ground pool no doubt they still swim.

Initially the salt system will be considerably more expensive. You have the cost of the salt cell,control panel and the salt for the pool. Over the long run though, the system will pay for itself. Salt is not used up so the only adding needed is what is lost during backwashing the filter, splashing and what people remove with them when getting out of the pool. IMO the salt system is a lot easier to maintain. once you have everything set properly, it will run and produce chlorine on its own. No more storing or handling harsh chemicals. Best part, you can leave for a month and come home to a clean pool instead of a slime pit. For more information visit

We put in a saltwater pool and the only problem we had was we chose a limestone rock coping. The salt ate away alot of the rock and we've only had the pool four years. So last summer, I switched to chlorine and am letting the salt level gradually lower with backwashing, swimming, etc. Just be sure you use an appropriate coping material with the saltwater pool.

What is the best coating for an inground pool?

Good research at I researched all the options they offer and read all the research. I like them because their site focuses on helping solve your pool problem, NOT just trying to sell you some product. In the end I emailed them about my problem. I got a phone call from the owner. We talked for about 5-10 minutes, and he said that I did not need to buy anything from him, and he gave me simple step-by-step instructions to fix my pool wall problem. I took his advise, and the pool is fine (cost me $200 in materials instead for $2000 in pool coatings). I am new to this also. I have to select a coating for an existing pool.

Suggesting coating (I don't know about Pebbletech, which is a surfacing more than a coating or paint), I would recommend to look to Ramuc, National paints manufacturers. Then the discussion will go on choosing between Epoxy, Rubber or Acrylic coating.

Not all these coating can co-exist or be used over old coating. Acrylic seems the easiest to apply but with a shorter useful life. AnswerMy gunite pool was resurfaced with fiberglass. It is smoothe to the touch and I use significantly less chemicals because fiberglass isn't pourous like gunite. AnswerNew surface for a Gunite Pool shell.

You can choose the more common marcite surface, this is a marble + white portland cement + additives mix for a surface which has lasted over 30 years when properly taken care of.

Secondly you could go with a finish of quartz + additives which is more durable and forgives more abuse, these finishes last and last most even have 10 -15 year warranties

Fiberglass coatings are also available for gunite pool shells and have options also.

Not to mention auto covers for all pools, chlorine generators, wireless controls, and lights of all colors, water features have never been more high tech. Your licensed pool pro is available to help you.

Many people ask me how can people justify owning a gunite pool with a very expensive quartz or diamondbrite finish? To help answer that question, I ask them, What's important to you?

Inevitably the answer is, "Everything is important" And those sucessfull owners are demanding pools that are gorgeous , have features that make every moment enjoyable, always want reliable and safe products, that also keep their value. good swimming.

Whatever finish you choose, avoid DiamonBrite. It stains very easily, is highly sensitive to chemical balance and a real nuisance. Our 2 year old pool needs to be fully resurfaced because the DiamonBrite blue finish is now streaked with grey. In our new FL development, Rottlund Homes selected Oasis Pools who recommended DiamonBrite over Marcite and PebbleTech. All of us regret following their advise. All of us, over 60 homes, are looking at replastering. Acid wash only temporarily fixes the problem.

How do you get rid of salty taste in pool?

TDS (Total Disolved Solids) in general make the water taste salty. Specifically sodium from the chlorine you add. Draining is the only way to get rid of the salty taste.

How do you convert from baquacil to chlorine if algae is present in the pool?

To get rid of algae in a Baquacil pool, the best thing to use is the Performance Algaecide. The algae will actually get worse if converting because you have to wait until the Baqua reading is at zero before converting which could take at least several days because the Oxidizer is designed to last for an entire month.

I can send you instructions by e-mail re converting from baquacil to chlorine and/or the saline system. E-mail me.

Can you use salt water in a hot tub and if so how do you do so while keeping costs down?

Salt water hot tubs have some misconceptions behind them.

  • It is not the same as the ocean. The ocean has tens of thousands PPM of sodium. (notice I used sodium, not salt) Salt water hot tubs (and pools) start out with only 1500 to 2100 PPM of sodium. A fraction.
  • All bromine and Chlorine start out as sodium. Bromine, started out as Sodium Bromide (NaBr). Chlorine (NaCl)......take a look at the box of table salt. Salt water hot tubs are nor corrosive then any other tub out there. Acidity actually come from other sources.

Okay, now that we understand what and where the chemistry comes from, lets look into how it works for our hot tubs.

  • We cannot use NaCl in a hot tub, it is affected by temperatures over 98deg. (which is every hot tub out there). So, we have to use a bromine base, that is not affected by heat, NaBr. This is of course the raw material used to make an active bromine, which is what kills the bacteria. We add, based on the size of tub, many gallons (or Litres) to the tub to bring the PPM up to the appropriate level. (between 1500-2100 PPM). The NaBr, is mixed up with the water and is now ready to turn into Bromine.
  • We turn the NaBr into Bromine by passing the water and NaBr over something called a "salt cell". This cell is made of graphite. (pools use titanium) As the water comes in contact with the surface area of the cell, the energy that is being passed through the cell releases the Bromine molecule and turns the sodium molecule dormant (but not gone). We now have an active, or FREE BROMINE. There is usually a dial that can adjust the strength of the cell, to give you more bromine.
  • As the bromine comes in contact with bacteria, the bromine is then used up, and goes dormant bringing it back to its original state (NaBr). As your hot tub circulates, it simply recycles the inactive back to active, over and over again. And because Na is a mineral, it does not evaporate with your water, so there is far less draining of your tub, and considerably less chemicals....There is a major cost savings.
  • If someone tells you that salt systems are not good for your tub, understand this. The reason for dumping a regular hot tub every 3 months or so, is because of the pucks and powders that you use in the tub, they are full of all sorts of fillers and the pucks are full of glues and binders that help make them dissolve slowly. This increases your ppm count, but more importantly it increases it with bad parts. FACT. Salt water hot tubs do not use pucks and powders(aside from the occasional blast after heavy use).... It is actually far better for your tub, they use only liquids. The liquids are much better for your tub, and dissolve much better then the pucks and powders.

How do you convert a pool to real saltwater?

How to convert a pool to real saltwater.

Add only sea water, just like a cruise ship pool operator would, dump it everytime your done for the day, and try like heck to get a health dept. permit.

You will find pumps and filters to handle salt water and heat exchangers to handle your heating needs on a commercial basis, Astral is one mfgr. you can try.

But again your first stop is going to be your local and state health dept for a permit to operate a commercial pool with sea water.

What does buffer and added hardness do for a saltwater pool?

Buffer and added hardness do the same thing in a salt water pool as in a fresh water pool. The buffer (sodium bicarbonate aka bicarbonate of soda) stabilizes the pH of your pool so that addition of acid or base doesn't change the pH very much. The hardness, mostly Calcium, helps achieve water balance to make the pool neither deposit (precipitate) excess Calcium Carbonate to your pool surfaces nor corrode (remove) Calcium from your plaster pool surface. The combination of pH, Total Alkalinity (adjusted for Cyanuric Acid), Calcium Hardness, temperature and Total Dissolved Solids determines whether your water is balanced. Just keep these values near their recommended amounts for your pool and you should be fine. If you're a techie and want the full formulas, do a Google search for "Langelier Saturation Index".

What is the cost and efficiency of converting a public 'chlorine based' swimming pool into a saltwater pool?

You will need 1 chlorine generator for every 25000 gallons of water in your pool, They run 1500-1700.00 each. It takes about 2.5 years to break even, If nothing breaks.The water is tons better feeling on your skin and you still need to keep PH in check add Pool conditioner and keep track of your phosphates.More info Kenny 801-232-5893

You also don't have to mess with chlorine tablets, granules, etc. Many of the newer chlorine generators are self-cleaning and easy to use. A good example is the Aqua Rite from Goldline / Hayward. You can see one here:

Does swimming in a saltwater pool damage your hair?

yes, salt is very drying! but during the hot summers, not swimming doesnt seem to be much of an option so before you go into the pool put conditioner in your hair... just enough to evenly distribute

How do you know if your pool is a saltwater pool?

Saltwater pools generally will have a salt cell installed within the plumbing usually after the heater. It is the cell where the chlorine is produced. It should have a cord on it that leads to a power center. Having your water simply tested for salt will not determine whether or not it is saltwater. Even pools using liquid chlorine(Sodium Hypochlorite) can have high amounts of salt if they haven't been drained in a while.

What size pump for a 5000 gal pool?

i also use a 5000 gallon pool above ground and i use a 1 1/2hp pump. with a sand filter.

Are Olympic pools saltwater?

Pools used in Olympic competitions are filled with chlorinated fresh water.

Can you turn a chlorinated aboveground pool into a saltwater pool?

Yes,but only if your pool is resin[that is constructed from 100% polymer or plastic]. It is not advisable to use salt in a "steel pool".

Salt in a steel pool is a lousy salesman answer. All Chlorine is made from Salt and the amount needed in your pool is insignificant to what kind of pool you have. Any pool can be salt

Will installing a saltwater system on a new pool immediately after filling with water but before the interior has cured stain the pool?

I have a salt water system and recently had my pool resurfaced. There was no staining. If you put your salt in the skimmer like you we're supposed to there should be no staining, If you put your salt directly into your pool it could stain from the minerals in the salt. If you used table salt there will be much less staining than if you used road salt.


You should NEVER use road salt or table salt. Wrong chemical make up! Follow directions on the "pool salt" bag. The salt goes into the pool and not the skimmer!! You must brush any salt that lingers on the floor until it is mostly dissolved. DO NOT add salt until the water has filtered for at least 24 to 36 hrs. or that recommended by the manufacturer or pool builder. Do not rely on other people to tell you what needs to be done. GO to the source -- builder - manufacturer. You should not have staining if the above basics are followed. Additionally, you must run the standard pool equipment for about 2 weeks or more. This gives the plaster time to cure properly. The salt system can and most likely be installed by the builder as he installs the pump and filter. The salt system unit will not be turned on until the plaster has cured. After the cure you must follow procedures on the proper start-up of the salt system.


Can i use copper algaecide in salt water system pool?

Answer : in short yes copper is fine, but...

I have copper-zinc mesh screens in all my collection baskets, i go to rummage sales to find 64' & before silver coins and single pieces of sterling silverware in bad shape; i put that in the baskets too. You can get broken sterling silver jewelry for pennies on the dollar, the cheaper the better. The cheapest sterling silver has the most copper, and turns black quickly. This means it's pretty reactive. Silver and copper in this form with sodium & chlorine ions in a salt water pool, along with the zinc kill off EVERYTHING. The reactivity of electrolyzed water on microorganisms is amazing.

I have a masters in biology from Indiana University and I'm a microbiologist that works for a large Indiana city muni-water dept. I work in a lab setting, i test for all contaminates in the cities public pools, including those found in the public schools.

There is a fellow from my university who uses Cavitation to kill ALL microorganisms in his pool without the use of ANY chemicals, his pool is pure water from the tap without ANY additives!!!

This is not impossible, but it is expensive!! And in a public pool system according to laws in our state it would have to have some amount of chemical that killed bacteria on contact, such as bleach/chlorine.

He is a private individual, If you would like further information just Google, Jet Cavitation, or impeller cavitation, in relation to microorganisms. Also Dynajet, and Hydrodynamic cavitation. This technology has been used for decades in the food processing industry, but if you have thousands to blow, why not.

I have cultured samples from my pool on a regular basis, my levels are cleaner than any public pool I've ever tested. The combination of silver,zinc,copper and the salt water even kills Cryptosporidium.

I have future plans of testing neem and tea tree oil in a pool.

P.S. Copper will stain your pool if you have light colored floor/walls and your hair if your grey or blond, I don't recommend it for newly dyed hair either. If your pool is a dark color you have no worries. Blue dye might help but that has consequences too, things like bluing agents, best of luck.

How do you get rid of rust in a vinyl pool?

I have the same question. A screwdriver was laying at the bottom of my pool throughout the whole winter, now there is a rust mark about 2in by 2in in the bottom of my pool. Does anyone have any suggestions on how to remove it without clouding my water or damaging the vinyl liner?

When backwashing a salt water pool will the water kill plants and flowers?

== Ok, the answer is yes, depending on what plants you are talking about, if you are talking about epsom salts that is a good thing for some plants. Also magnesium, and try to direct your pool discharge away from your landscape. The art of pool water discharge is easy. PVC pipe is very helpful, or try a flat rubber hose as an alternate. == == No, salt is actually good for plants believe it or not. I know for my tomato plants, I put a little bit of epson salt in the hole where I plant my tomatoes, unless of course you were to flood your plants completely. I agree some salts are necessary for plants however the type of salt used in most swimming pools is Sodium Chloride or Common salt, while a bit of this stuff is not necessarily going to do too much harm you could end up with a build up of salt that will harm the soil and some of the plants. Salt contamination of the soil is a big problem throughout Australia. However a new salt water system system using Magnesium and potassiums chloride is actually good for the plants, but this stuff is only just coming onto the pool market.

Does the salt in a saltwater swimming pools harm the equipment?

Salt Harming EquipmentA salt system can harm the equipment in a "runaway chlorine" environment which can be common if the unit isn't operated properly or if water isn't tested and balanced regularly. In a runaway chlorine environment, the chlorine created by the salt system could potential dissolve the heat exchanger in a heater in a couple of days.

The salt can also be harder on the pump seals and the salt corrodes motors and equipment in the case of leaks.

Which is best to clean pool water the ozonation system or the salt system?

The problem with an ozone system is that it is only a partial solution still requiring some addition of pool chemicals and still requiring a high level of monitoring and maintenance.

There are numerous advantages in installing salt water system into a new or existing swimming pool: • Lower operational costs -- eliminates the need for chemical chlorine and reduces maintenance requirements. • Increased safety -- eliminates the risk of having toxic chemicals around your house. • Increased swimming enjoyment -- no more stinging eyes or chlorine odor on skin and clothing. The mild salt water also provides a more luxurious bathing experience.

I thought that salt systems convert the salt to chlorine in the pool. So, you don't have to store chlorine (you store salt), but you still end up with chlorine in the pool (and it's subsequent impact on skin / hair / breathing of fumes / bathers etc.).

Also, apparently ozone + ionization + very small amounts of chlorine etc. (in a pool with water mixers that can be added cheaply) works well.

If you use a robotic automatic cleaner they filter out lots of particles, including very tiny particles, and so ease the load on the main filtration system. And they keep the pool extremely clean.

I am in the saline pool system business, but please be assured my comments are based on facts, not biase. Ozone is a very good oxidizer, but has two major drawbacks for use on average to large size swimming pools. 1. Due to its half-life (of about 20 minutes) is is difficlut to disperse throughout and keep in the water. You cannot maintain or 'measure' a residual of ozone sanitizer in the water, especially with reasonably priced UV (ultra violet) type systems and larger output CD (corona discharge) systems are very highly priced. 2. Ozone does not kill algae and you must maintain a residual of 'chlorine' (or similar) in the water. Ozone by itself is not allowed in 'commercial' (pulic) swimming pools, but is OK if there is measurable residual of chlorine to go with it. A saline system on a pool does the entire job of sanitizing the water, without requiring the support of of any other type of oxidizer/sanitizer. Its effectivemness can be measured with a normal pool test kit, it eliminates the need to manually add any pool-chlorine, algaecides or 'shock' chemicals. Its best feature is the water quality and swimmer comfort which it offers (no hair and skin damage, not chemical odors).

Neither system can be defined as "The Best". Both Ozone and Salt systems have many drawbacks. Both systems are very climate dependent. Both systems generate chemical additives to your pool. Both systems require significant monitoring to avoid cloudy water and algae outbreaks. I agree that the short life span of the "Ozone" makes any size pool coverage inadequate. They only treat the area directly around the discharge point and generate Disinfection By Products(DBP) in the process. Salt systems require Carbon treatment, generate DBP, and leave a residue on your pool and pool equipment. Salt water is not good for the filter system or heater.

Ultraviolet Technology offers a refreshing alternative to pool sterilization. Systems like the HalcyonRx ( are very effective and low maintenance. UV destroys a broader amount of Bacteria, Germs, Virus and Algea than all other systems. Municipal water treatment facilities are converting to UV above all other technologies for Drinking Water treatment. With a minimal amount of residual alternative sanitizer (ie. .5 to 2.0 ppm Chlorine for example) UV does not generate any chemicals, adds nothing to the pool, and destroys DBP. You can not over treat your pool with UV. Annual bulb replacement and tube cleaning is all the maintence required. The Halcyon Rx comes with a 5 year limited warranty which makes it the most cost affective system available.
