Swimming Pools

If it is a round pool that is 10 feet wide and has 3 feet of water then it contains 1,770 gallons of water.

No!!! Under no circumstances should you drain a fiberglass in-ground pool. Unlike the standard in-ground pool, the fiberglass pool base is unreinforced concrete or other hard surface material that was applied directly to the soil in a thin layer. It is only there to allow the fiberglass to be sprayed on and form a hard shell. The weight of the water is what holds the fiberglass in place. If you drain the pool without refilling it immediately, you will allow external ground pressures and/or ground water to buckle the sides or bottom and you will have the fiberglass completely redone.

It depends on whether the pool is considered "enclosed" inside a pool house or not. The assumption in such case is that the pool house prevents "outside" air circulation which enables the humidity inside that "house" to be maintained at a high level which minimizes evaporation. It goes without saying then that if you keep the doors to your pool house open then you loose much of the evaporative benefit of having the pool enclosed. In any case, high ambient outside air temperature will increase the pool evaporation rate but an enclosure should slow it down. Pool covers can also decrease evaporation rate. More input from FAQ Farmers: * Go to Arizona edu. There you will see a contour map of the U.S. providing annual evaporation rates in inches of loss per year. Find the rate for your area. Divide the rate by 365 to get the daily rate in inches of loss per day. * If you are concerned of a leak place a bucket of water on the steps of the pool and fill it so that the level equals the pool(u might have to weigh the bucket down with a rock or something) check the level the next day to see if they both evaporated the same.

Area of pond = 5 x 10 = 50 square meters

I assume your question is "How to level the ground for the installation of swimming pools" The answer is for a yard size pool you may have to rent a small grader such as a "bobcat" combination front end loader with a blade and grading attachment. These are widely available in North America and the Caribbean.

Acid lowers the PH number. You want the pH to be between 7.0 and 7.4. To raise the ph you can use baking soda.

You will need 17.5 square meters of water (17.5 tonnes) to fill it fully. The conversion to gallons depends on whether your talking about UK gallons or US gallons. That equates to 3850 UK gallons or 4623 US gallons. Hope this helps

Every thing exists under the same laws of Gravity. many things seem lighter in a swimming pool because they are relatively lighter in a heavy medium like water rather the light medium like air. Nearly every thing falls to the ground in air. however there are a lot of things that float or go up in water because they are lighter then water. this rule applies to every thing even things that sink.

An Endless pool is a pool that uses a current to give the benefits of swimming in a larger pool without actually having one. An Endless pool is more of a piece of workout equipment. A person can buy an Endless Pool from the Endless Pool website.

Yes it can. As long as you get the dose right for the pool it is the chosen sanitiser for most commercial pools. Follow the safety advice, keep the PH in balance and maintain good water quality. Sodium Hypochlorite is a wonderful product if used right.

I am in phoenix arizona. I have a 12-14,000 gallon in ground pebble tech pool and a 400,000 btu natural gas heater. Would like to know costs to heat pool of in phoenix, with a natural gas heater. Please state approximate pool size, in gallons and if you heat your pool a few times a month or all month long. Obviously winter would cost more than summer.

Marco polo, chicken fighting (if allowed) its where a strong person puts another person on their back, and you have two or more people do that, and the people on top try and put each other in the water. The last person remaining wins. its really fun to do :)

Here are the possible problems. 1. Is the backup valve stuck in backup? 2. Is the pressure correct? Wheels turn 28-32 RPM. 3. Is there air in the filtration system? 4. Are the hose floats in the proper placement?

OR

Air entrapment within the housing. Tilt the unit back and forth while holding it under water - - - watch for air bubbles then let it go.

Oil gets in a swimming pool because someone grabbed a bucket of oil and threw it in the pool.

First find the area of the cylinder in sqft.

V= (3.14) x .5' x 40' = 62.8 sqft

1 sqft holds 7.48 gallons

62.8 x 7.48 = 469.74 Gallons

The Lincoln Memorial Reflecting Pool is the largest of Washington, D.C.'s reflecting pools. Located directly east of the Lincoln Memorial, it is a long, rectangular pool visible in many photographs of the Washington Monument. It reflects both the Washington Monument and the Lincoln Memorial.It has a depth of approximately 18 inches (46 cm) on the sides and 30 inches (76 cm) in the center. There are other reflecting pools: http://en.wikipedia.org/wiki/Reflecting_pool

It sounds like fun but dangerous. If you are a dare devil it would be an interesting challenge but if you send it into myth busters it would be fun to watch!

What ever temp that is comfortable for you or your family.

There could be any number of reasons, ranging from simple evaporation to slow leak.

it's the same as when ever a person gets water on their skin. Skin is waterproof.

With either a skimming net or get an effective floating pool skimmer

The original question was the better of the two questions.

Is it ok to add muriatic acid while the pool is in use?

When is the best time to add muriatic acid?

You should either wait until no one is going to use the pool for a while. It is not a good idea to add chemicals to the pool while someone is in it. Best to add chem. first thing in a.m. before use - then let circulation distribute those chem.

Is it legal to put an ingroud pool in the city limits

you have to aid a conditioner or stabilizer with cynaric acid in it.

The main difference between stream pools and ponds is that stream pools are dynamic water bodies formed in the current of a flowing stream, where water collects and slows down, often creating deeper areas. In contrast, ponds are typically still water bodies that can be isolated from flowing water systems. Stream pools are influenced by the flow of the stream, while ponds are more stable and can support distinct ecosystems.
