how do you keep a 4 foot swimming pool clean even though you are running the filter.bottom still turns green?

Answer 1

Get an Aquabug. They clean the bottom of the pool (it's like a little vacuum). Either that, or you need to get better chemicals.

Answer 2

Proper water chemistry, filtration, sanitizer level and cleaning are the secrets to a crystal pool. You are lacking one or more of them.
Get your water balanced ( Total alkalinity, Ph, Cl in that order) or best to take a sample to your local Pro, he's got a better lab and can test for more things more accurately. Let him know you have an algae issue. Vac up what you can. If a sand filter, do a quick vac on waste or drain, having previously topped the pool right up, otherwise you may soon see the algae shoot back out of the return if you do it on normal "filter" setting. Sand filters will only get so much of it, before the algae makes it through the sand bed. Brush what's left to get it into the water column for you filter to deal with somewhat and to greater expose it to chemical treatment . Clean that filter out no matter if it's a sand or cartridge. It's always a good idea to keep the pump circulating at least 18 hours a day, in this case you want to run it 24/7 until the issue is resolved
Now you can add shock and algacide. As a rule of thumb, double your normal dose as soon as you see green. If you wait, it will get worse. Algae spores will double in number in a 24 hour period. Use a Poly Quat algacide (specify that in the pool store). It's expensive, but works the best.
Covering the pool doesn't stop algae growth, it can actually increase it, especially if you don't have proper water balance True it does stop un stabilized chlorine from getting zapped by UV rays, but it also doesn't allow the pool to off gas. Keeping ammonia in and actually feeding algae. No pool is meant to be covered 24/7.

Answer 3

Your going to have to use chemicals to keep a pool that size clean. It may be an above ground pool, but it still will need chlorine, and other chems to maintain clarity, and safety. You can take a water sample of your pool to the local pool supply company, and they will test the ph, and other levels (usually for free, or very cheaply) in hopes of selling you their chemicals.
Also, do you cover your pool when not in use? This made a big difference in ours. You can keep a hose near the ladder, and get everyone entering the pool to hose off first, this sure helps, believe it or not. Good Luck!!

Answer 4

Are you checking the Ph and Chlorine levels and making the proper adjustments? A properly filtered pool should not turn green if the ph and chlorine are adjusted right.

Have you backwashed the filter lately?

Answer 5

The easiest and cheapest method is to cover it when not in use. If no light gets in, the algae will not grow.
Otherwise, as suggested above, by all means, break out the chemical warfare.

Answer 6

Put algecide in it. You need to use pool chemicals. filter is not enough

Answer 7

treat it with chlorine, you can buy pool supplies at most larger stores like Wal Mart.

Answer 8

are you shocking the pool once a week?

Answer 9

chlorine
