I own and operate a small pool construction/service business, in my experience corona discharge ozone units sized properly are a wonderful addition to chlorine treatment. they do NOT replace chlorine but do reduce the amount needed to maintain 1.5 ppm and help maintain a much nicer cleaner looking and smelling pool. ozone is an extremely strong oxidizer and burns away many impurities instantly but provides no residual affect or treatment for "dead-spots" uv ozone generators in my opinion produce to little ozone to be effective and most that I have tried burn out in no time.

PS i have no experince with salt generators I have read alot about them but have not seen any in my area yet


I will start by saying that I DO work for an Ozone Generator Manufacturer. I partially agree with the above answer as far as Ozone not being a "stand alone" system. Ozone has a very short half life so when the pool pump shuts off the Ozone production is stopped as well. You still need to maintain 0.5 to 1ppm of Chlorine or Bromine residual to act as a "buffer" and sanitizer.

The part of the above answer that I DON'T agree with is the Corona Discharge (CD) statement. There are 2 different ways to produce Ozone on site at a residential pool/spa application as follows:

1. Corona Discharge (CD) - Ozone is created by creating an electrical arc over a tiny gap on a metal "chip" inside the unit. This initially creates a large amount of Ozone, but the "chip" is very short lived. The problem with this method is that unless an air dryer or prepared oxygen (tank) are used, Nitric acid will quickly build up on the chip, eliminating Ozone production within months.

2. UltraViolet (UV) - With this method, Ozone is created by passing ambient (outside) air across 1 or more specific wavelength UltraViolet lamps. The amount of Ozone produced with this method is less than that of the CD method, but still more than enough for the intended applications (pool and spa water). The UltraViolet method will produce sufficient Ozone for roughly 10,000 hours before a lamp change is needed.

The other important factor when looking at an Ozone system is the installation method. These systems can either be installed on the suction or pressure side of the pool pump (depending on manufacturer) which will make a large difference in the effectiveness and benefits of the unit. If the unit is installed on the suction side of the pump the Ozone is injected into the highest pressure point of the system which is between the pump and filter. This forces the Ozone mixture into the water and uses the filter as a reaction chamber, giving the Ozone adequate time to oxidize the non-living bather wastes in the water. As a "side benefit" this installation also extends the time between filter cleaning as the Ozone degreases the filter as well. If the Ozone is installed on the pressure side of the pump, it doesn't have enough time or pressure to effectively oxidize the water, it mostly just runs along the top of the return line and off-gases when it gets to the pool returns.

What is your options for hot tub chemicals?

Options for hot tub chemicals include standard bromine or chlorine for disinfectant, pH plus and pH minus to adjust pH levels. Some hot tub owners who want more environmentally friendly solutions that use less chemicals are using ozonators, bromine or chlorine salt generators (salt systems), Waters Choice enzyme treatment which reduces chemicals needed, and mineral sticks.

Ordinary salt is a compound formed from sodium and chlorine.

Can you have a salt water hot tub and a chlorine pool without cross contamination?

You cannot "contaminate" a chlorine pool or spa with salt or vice versa. Chlorine starts as salt. Chlorine generators use salt to make chlorine. Therefore your "salt" spa is already a chlorine spa, you are just not putting chlorine tablets in it. It is a very common misconception that a salt system is some how different than a chlorine system. There are no "salt generators" and the salt does nothing other than allow a "chlorine generator" to produce chlorine. We get this question almost every day and it's generally because customers are "sold" not "told" about the product they purchased. If you were expecting anything other than purchasing a device that makes chlorine from salt, you will be disappointed. Pool & Spa

Can you use salt in a swimming pool without a chlorine generator?

Absolutely! It is very common for customers to want the feel of saltwater without the chlorine generator. ALL CHLORINE POOLS CONTAIN SALT. Chlorine reverts back to salt when used so every pool that has chlorine in it also has salt.

Is the salt or chlorine more abrasive for your skin?

Chlorine is more abrasive for your skin. Salt is much more natural and better for you. But if you have a salt system in your pool, you are still producing chlorine.

Do saltwater pools attract more snakes than chlorine pools?

Here is the deal. a "salt water pool" IS a chlorine pool. Only difference is, on a chlorine pool u add chlorine. In a salt pool u add salt and a "Salt Generator" turns the sslt into chlorine... so really both pools use chlorine.... Just saves u the trouble of messing with chlorine and chlorine shocks..

Can I Mix salt in a chlorine pool?

Is a salt water or chlorine pool better?

A Salt water pool is a chlorine pool. The difference is that in the case of a saltwater pool there is a chlorinater fited inline that converts the salt into chlorine automaticaly, Meaning that you don't have to purchace any chlorine to keep up chlorine levels.

Is it better to have a salt water pool than a chlorine pool?

A salt water pool is a chlorine pool. the difference is that in a salt water pool the chlorine is added automatically by a chlorinated that works electronically and with a chlorine pool you have to put the chlorine in your self. Salt water pool are by far the more pleasant to swim in. Chlorine because it will kill germs

Does chlorine contain salt?

No, chlorine is an element, consisting only of chlorine atoms. Common table salt contains chlorine in the form of the chloride ion (Cl-)

Can you mine chlorine?

No, its a gas. You can't mine it.The usual source for Chlorine is common salt, as found in salt mines, salt pans and the sea. Salt is a molecule consisting of one atom of Sodium and one of Chlorine. By breaking the chemical bond between them, Chlorine is released.

How do elements sodium and chlorine differ from the table salt form?

sodium is not eatible nor is chlorine. Chlorine is a chemical and when mixed with the sodium it forms a new eatible compound and this is salt or table salt.

How much chlorine does table salt have?

Exactly half the atoms in salt are chloride ions. Since the chlorine atom is a bit heavier than the sodium atom, salt is about 61% chlorine by weight.

What element is combined with chlorine in common salt?

Common salt, or table salt is sodium chloride, so you would combine sodium with chlorine.

Does salt water evaporate faster than chlorine water?

No, salt water does not evaporate faster than chlorine water. Salt water contains chlorine. Therefore, they both evaporate at about the same rate.

Is there salt in chlorine?

Sodium chloride (NaCl) contain chlorine.

What does the chlorine inside salt do?

Chlorine (as chloride, Cl-) is the anion.

What is the percent composition of chlorine in salt?

By atoms it is 50% sodium and 50% chlorine. By mass (sodium is 23.0, chlorine is 35.5, salt is 58.5) is 39.3% sodium and 60.7% chlorine.

What do people use to clean pools insted of chlorine?

They can use salt or chlorine but most people choose salt

Do you have to buy a salt chlorine generator to have a salt water pool?

Yes. The salt is run through a chlorinator that changes the salt to chlorine. It won't do it by itself so you have to buy the generator to do this.
