Step by step on cleaning a green swimming pool?

(1) increase the amount of chlorine in the pool

(2) get an algaecide from the pool shop and follow the directions on the bottle ( I like copper based algaecides as these seem to last longest in the water.

Unless the infestation is very serious you should have the situation under control in a couple of days. However these are not always suitable for salt water pools.

(3) if you find that the infestation is so bad that you are unable to clear up the water go to the pool shop and get a floculent follow the instructions on the container.

Where do you put the chlorine tablet in an Intex pool?

Yes you can, but we noticed some staining to the floor and the concentration of chlorine near the tablet will kill things like small animals and insects. Kids would play with the tablets and hurt or blind themselves. Chlorine was one of the first poison gases used in ww1, you need to be careful. The floating containers for tablets are not that expensive.

How can you measure pH levels in a swimming pool?

This would depend on what sanitizer you are using: chlorine, bromine, salt generation, biguanide (Baquacil, Biogaurd), etc... However as with most systems, the best way to ensure accuracy is to have it professionally analyzed by a local dealer at least once a month. As far as home testing goes, drip tests are typically the most accurate way to test biguanide and chlorine pools, while strip tests are far more convenient and also cover more water balance criteria.

How long is a long course swimming pool?

50 meters. This is the course used in the Olympic Games, the Pan-American Games, the Pan-Pacific Championships, and USA Swimming's Summer Nationals. The standard Olympic pool is 50 meters long by 25 meters wide, with 10 lanes of 2.5 meters width, and a minimum depth of 2 meters.

How much algaecide do you put in a 24 foot round pool when closing for the winter?

Assuming that your pool is 24 Round 52" Walls, Roughly 14,435 Gallons. Amount to be used will vary depending on the algaecide used. We normally recommend refering to the label of the algaecide you are using. We use Blue Wave Halt50 Algaecide with our winter closing chemical packages which recommends using 5oz per 10,000 gallons for booster dose.

In Ground Swimming Pool Installation?

I assume that you are shopping for a pool and are looking at an above ground. I have had three above ground pools. No nothing was wrong with them. We just keep moving. To answer the question: NO, the uprights are not buried. They are not even dug in to the ground. Make sure you pay a professional to set it up, it's money well spent. The ground should be leveled, then a stabilizer ring is put down in the shape of your pool. Then the uprights are placed in that ring. The uprights really do nothing more than join the top and bottom rails of the pool and give a little stability to the wall.

Enjoy.

How do you replace bearings on hayward pump?

Get a workshop manual for the pump and follow the instructions.

What do you do if air pillow pops while pool is frozen?

An air pillow is only present for the management of rain water on top of the cover. It is not designed tostructurally safeguard the pool. Do not touch the pool once it has frozen water upon it. You may cause more damage than leaving it alone.

What is the Formula for water in swimming pool?

The easy way to do this is to apply a simple rule of thump that for every 100 m2 of pool surface area, 4-5 m3 of balance tank capacity is needed. For example, given a pool size 50 x 21 (1050 m2).

Taking 5 m3, the balance tank capacity would be 52,3 m3

What is the lane size for a junior Olympic pool?

A pool that is used for the junior Olympics (I'm assuming that's what you're referring to) is either 25 yards or 50 meters long, depending on the country you're in. In the US, the JO size is 25 yards.

AnswerThere really is no Jr. Olympic pool. If one is referring to a pool that is used for the AAU Jr. Olympics, the pool dimensions are the same as full grown Olympics. If one is referring to a pool that is smaller than an Olympic pool (Jr. in size) Then a short course pool is usually found. Here are the standards used for Olympic pools. I found this on the usaswimming.org website. Follow the following link.

AnswerThe lane size for any pool used in USA swimming championships and international competition is 8 feet 2 1/2 inches or 2.5 meters from divider to divider with approximately .45 meters or (1 foot 6 inches)of additional open water for the outside of the outside lanes. AnswerSince this is not a internationally recognized size, at least in US a Junior Olympic Pool would be either 20 meters or 25 yards. Neither of them truly is half of Olympic size pool.

ANSWER

Competition pools in the US are usually one of four lengths. They are 25 yards, 25 meters, 55 yards, or 50 meters. These lengths are chosen because only pools of these lengths are recognised for the establishment of record times by US swimming regulatory bodies such as USA Swimming. Recreational pools come in all shapes and sizes and are not CERTIFIED. Competition pools must be certified by an engineer to be within very strict limits so as to provide a standard length for setting records. International rules are different (see FINA ). If you want to determine conversions from meters to yards it is generally acceptable to add 10% to a yard time to yield a close approximation of a meter time. This is true because a meter is about 3.37 in longer than a yard. Mile distances are rounded to the nearest full length. For example a mile in a yard pool is 70 lengths or 1750 yds, actually 10 feet shorter than a mile. The best way to determine whether the pool you work out in is 25yds or 25 m is to get a tape measure and measure the pool.

Why is a salt water pool affecting hurting your sinuses?

A properly dosed salt water pool should be better on your sinuses then a freshwater pool. as it is more in tune withe the chemistry of your body. Salt concentrations in salt water pools are about the same as that found in your tears. Perhaps you should check that your chlorininator is not set too high. too much chlorine can lead to irritation in places like the sinuses.

How do you calculate how much chlorine to put in your pool?

1 gallon of 12% strength liquid chlorine will raise 120,000 gallons of water approximately 1ppm. For 10,000 gallons it takes about 9oz. to achieve 1ppm. PPM means parts per million not parts per moron. A 1-1.5ppm chlorine residual is usually sufficient to maintain a swimming pool as long as it is in a free and not combined form (chloromine). Public pools are closed down if the chlorine level exceeds 9ppm. 1 gallon of chlorine in a 10,000 gallon pool will exceed 14ppm. Use an oxidizer such as potassium monopersulfate to keep the chlorine in its free state and you won't turn your hair green (copper precipitates) or dissolve your children. If you're using calcium hypochlorite a quarter pound will raise 20,000 gallons to 1ppm. The practice of overdosing a pool with chlorine once a week is for lazy people that don't know chemistry or math. Chlorine is an oxidizer and can be harmful in large doses as it is easily absorbed through the skin. Take your choice.

How much water do a 15 ft round pool hold?

A 15-foot round pool holds approximately 4,700 gallons of water when filled to capacity. To calculate this, you can use the formula for the volume of a cylinder: Volume = π × radius² × height. For a typical above-ground pool with an average depth of about 4 feet, this results in roughly 4,700 gallons. Keep in mind that the actual volume may vary based on the exact dimensions and shape of the pool.

How many gallons of water for 310 square feet?

This question requires a lot of assumptions to answer s the best I can do is give you several answers and hope one of them hits the mark. One cubic foot contains 7.48 gallons. 1. There is no gallons of water in 310 square feet because this is a 2 dimensional figure. 2. There are about 232 gallons if you filled that area 1 foot deep. 3. There are about 464 gallons if you filled that area 2 feet deep. 3 There are about 696 gallons if you filled that area 3 feet deep. We could go on but I am hoping this answers your question.

How many gallons of water are there in a 15 X 24 foot swimming pool that is 4 feet deep?

If the pool is 15 feet long and 4 feet wide, that would be 60 sq. feet of area. Now you would need to know the depth. Multiply 60feet by the depth and then multiply by 7.48 gal. per sq. feet for the total capacity. Is the pool round by any chance?

How much water does a pool use?

Almost nothing if theres a cover on it, otherwise you can lose a few gallons on a hot sunny day.

Can a well be used to fill a 5000 gallon swimming pool?

Yes, but your pump in your house will be running for a long time. Assuming you

have well that yields approx. 5 gallons of pressure per minute (3 gal is low, 7 gal

is high) 5000 gal divided by 5 gal. per minute = 1000 minutes/60 minutes per hour=

16.67 hours. It will take over 16 hours to fill the pool if you run your garden hose

non-stop. This may burn up your pump in your house. I would run the hose about

5 hours per day and you will fill your pool in about 3 days. That way the pump is

not overworked. You may want to time the water coming out of the garden hose

by filling a gallon jug to see how much pressure you actually have. Or you could

simply have a bulk-water company fill the pool in approx. 15 minutes but it costs

about $200 for this option.

How many gallons of water are in a kidney shaped pool that is 30 x13 and from 4 feet to 6 ft deep with a connecting spa?

30 x 13 x 5.9 (gallons per cubic foot for that particular shape) x 5 (average depth) = 11,500 US gallons, not including the spa since you gave no specifics on the spa.

How do you drain water out of your inground pool that has a bottom drain?

We just drained our 33,000 G. inground gunite pool for the second time. We used our commercial pump to remove the water. As you get to the bottom of the pool there is a cap next to the drain in the bottom of the pool that should pop out because of the ground water pressure. We then place the pump hose over that hole to control the groundwater coming up through the hole. Note that before we get to that point, we've already taken bleach (weed spray cannister) and sprayed the walls with the bleach and washed with water. The pool is sparkling clean. Better than an acid wash. Once completely cleaned we place the cap back on and place two garden hoses in the pool and start refilling. It takes two days to refill. Good luck!

Ans: The drain grate at the bottom of the pool is not actually a drain as in bathtub drain. It's purpose is not a drain but is there only to circulate the lower portion of the pool water. That grate's plumbing is connected to the skimmer which is then connected to the pump. It is like a closed circuit plumbing installation. To drain water off you need an an external sump pump that you drop into the pool - usually with a garden hose and an electrical cord attached. Some sump pumps can use hoses up to 2" in diameter.
