A fence can be anywhere around a pool it can be right at the edge of a pool or even just surrounding a pool.
As far as I know there is no law against it. Pools are private enterprises and can(and do) make their own rules and by (boardwalk) laws. For example some swimming pools in New Jersey with appropriate secure lighting allowed night swimming, others did not. some may have required caps or shower helmets, etc. consult your swimming site!
In my opinion, none! Stick with Marcite. I completely disagree. With 19 years experience in the restoration of older swimming pools, I have learned that fiberglass swimming pools are the best of the best. My business is limited to older pools, so my expertise is in swimming pool longevity, therefor my answer is: If you expect to own the pool for more than 15 years, and if you can afford a gunite, concrete, or fiberglass pool, you should definitely choose fiberglass. On the other hand, if price is the issue, you should choose a vinyl liner pool which will cost about half that of gunite, concrete, or fiberglass. Unfortunately, when you decide to sell, a vinyl liner pool will actually detract from the value of the home. On a geographical basis, Florida is a great place for a fiberglass swimming pool, but so are the rest of the Continental United States. Location does not matter, regardless of what you may read in these forums. The only thing that does matter is that you never empty the pool without professional assistance. The same rule applies to vinyl liner pools. The only advantage to gunite and concrete pools is that you can usually get away with emptying the pool without help. But even concrete and gunite pools can be seriously damaged if the pool is emptied without consideration for hydrostatic pressure. Just like construction of a gunite, concrete, or vinyl liner pool is quite important, so is the installation of a fiberglass pool. It is not a DIY project for most people. Another important factor with fiberglass is the manufacturer of the pool. I consider the very best to be San Juan pools because no San Juan pool owner has ever contacted our company for restoration before the pool was at least 27 years old. Finally, there is no such thing as a surface that will last a "lifetime", unless you consider a lifetime to be 20 years or less (excluding only San Juan). Frankly, I thought 20 years was a "generation", but the pool manufacturer's and builders seem to have the two terms confused. Fiberglass requires considerably less chemicals and far less maintenance that any other pool currently in existence.
if pool is 25 m long , 15 laps is 25 x 15 = 375 meters, which is 3/8 kilometer
2.5 meters
distance???? Do you mean how far can a swimming pool travel???
As far as I know, regulation dimensions for a short course pool is 8 lanes wide by 25 yards long. Long course pools are 8 lanes wide by 50 meters long. However, I have seen a lot of competitions in 6-lane pools, and some in 10- or 12-lane pools. One time, I went to a swim meet in a 4-lane, 20-yard pool, but that was pushing the limit.
It depends on your pool. It is 1 length of an Olympic pool.
It depends on the length of the pool. If you are swimming in a 25 yard pool, 300 yards would equal to 12 laps.
I think I did, I am a waterpolo player someone had mono in the pool, now two of us have it do far.
25 yards
Not if you know how, plus it's the best exercise for the body. However this also depends on where you are swimming at. It is far more risky to swim, say, in a river then in a swimming pool.
You can't, unless you screen the pool the only thing you can do to decrease the irritation is install a floating pool skimmer as this will get rid of floating materials far more quickly.
In a long course meter (LCM) pool, 50 meters equals one length of the pool. In a short course meter (SCM) pool, 50 meters equals 2 lengths or one lap of the pool.

The smallest depth they can be (as I know so far!!) is 2 meters deep. Still rather deep.
