The pool is still cloudy even with all chemicals balanced and a clean filter? I tried the clarifier stuff too and its still like chalky. How can i get it crystal clean?

Cloudy water is the bane of sand filters!. I suggest letting filter run day and night. Do not backwash until the pressure rises 8 - 10 pounds above clean starting pressure. Do not try to vacuum or stir up the sediment. when water clears, vacuum to waste. Keep the hose running while vacuuming. A dirty filter is a better filter (up to a point). At a higher pressure the filter will trap more of the fine particles that are clouding your water.

Otherwise chemistry fine?
whenever someone is vague about chemistry residual readings, but provide a pH reading, I'm always Leary.

• bring pH up to 7.6
• Balance Total Alkalinity at 120 ppm
• Bring Hardness to at least 200 ppm
• Keep Chlorine level at least 3.0 All the time
• ISO Cyaniric acid / stabilizer at least 30, not exceeding 80 ppm
• Use a Natural Clarifier weekly - rate = 1 ozs per 5000 gallons
• Use Algaecide (not from Kmart!) weekly
• Clean filter whenever pressure approaches 8# over starting
• Filter for at least 1 turnover per day. This is usually 8 hours in most regions

Follow this, should be good

Thank you for posting your question here on Fixya.com.

You need to be able to test at least chlorine, salinity, ph, alkalinity, and stabilizer. The best way is using test strips. If you have a sample of water tested at a pool supply store that will work too but frequent transportation is more costly than strips. The salinity should be about 3000 ppm, Chlorine should be between 2 and 4 ppm, alkalinity should be between and 80 and 140 ppm and the stabilizer should be between 30 and 50 ppm. Some say up to 100 ppm. Unfortunately higher stabilizer reduces the chlorine's ability to kill algae, etc. When the water becomes cloudy it is likely low on chlorine and is about to turn green. If the test shows low chlorine level then I would add shock to 10 ppm chlorine. If the filter system is working correctly then it should clear up fairly soon. I would not let anyone swim until the chlorine is between 2 and 4 ppm and you can clearly see the pool bottom.

first balance the pH and then test other chemicals BALANCE pH FIRST. and rum pump continuously for a few days. and then about 8 hrs a day.

How long is it since the sand in the filter was changed? How long has it been installed? If the water is clean but cloudy, get some kind of flocculant from your pool supplier. Follow the instructions carefully as your pool will need to be bavkwashed on a frequent basis.

How long has it been since you cleaned the cartridge in the filter? If it's been a while, I'd recommend cleaning it thoroughly with a filter cleaner (degreaser). This will help to filter out any small particles that can cause cloudiness. I'd also recommend that you increase the salt production on your salt system. The normal range for chlorine is 1-3 ppm. You're too low at 0.2. If all of these things are done and the pool is still cloudy, I would add a clarifier. FYI: too much is not better when adding clarifier!

You may have to change the sand if you never have. Or if it's not too bad you can "clean" it. When you removed the plug form the pool, there should actually be two parts. This first part threads directly into the filter, and has a screen on it to hold back the sand. The second one is the plug. This is the only part you should remove, except when changing sand etc. Even if the pool filter is working you can have cloudy water. See you pool supply, and try a floc to help settle dissolved solids in your pool. You add this, run the pump awhile to mix, turn pump off overnight, and then vacuum everything next day. Then turn pump back on.

You probably have too big of pump. It is pushing the finer stuff right back into pool. Try adding a clarifier. Don't backwash either until the pressure goes up.
