    Default Can't seem to get the pool clean

    I've discovered a dirty layer on the bottom of my pool and when I try and vacuum it, it dissolves back into the water. Though it looks clean when I'm finished by the end of the day the bottom is cover again. Had a pool for 6 years but never this problem. It all started when I noticed the water was cloudy. I added clarify and the next day I had this issue. The water was no longer cloudy but the bottom was very dirty.

    Small pool, 8,000 gallons. Chlorine and PH are fine. Filter sand replaced 2 years ago. I cycle the water through the pump every day for 2 hours. Should be enough based on pump power and size of pool. Back wash often,
    until the water runs clean. The water jets are pointing up in hopes too vacuum the bottom before the
    water movement dissolves the dirt. If I point them down the dirt dissolves back into
    the water in minutes and unable to vacuum any of it.

    Any ideas?

    At times the clarifier just doesn't do it. Sounds like you should Flock your pool. One large jar of Flock agent should do it. Any pool store has it.

    1. Put your filter on recirculate.
    2. Dissolve some of the flock powder in a bucket of water, stir and throw into pool. About 1/8th of the flock in the bucket at a time so that you are dissolving most of the powder.
    3. Fill your pool to the top with water.
    4. Run pool in the recirculate mode for about 6 to 8 hours then turn off.
    5. Do not turn on the pool again. Wait overnight and you should have a layer of gunk on the bottom in the morning.
    6. SLOWLY vacuum your pool in the WASTE setting on your filter. You DON'T want this stuff going thru your filter.
    7. You will be taking the gunk and water out of the pool so you will need to be filling with water as you vacuum.

    That should do it. At least that's what works for me about twice a year. Good luck.

    It’s probably 1 of 2 things. First, with a sand filter and sand 2 years old, it’s time for a change. Second, you may be backwashing too much. If you backwash before the filter pressure increases 10lbs from the previous backwash, your sand will be “too clean” to catch fine particles and by backwashing often, you lose the effectiveness of the sand as it destroys the microscopic points on the sand particles that catch the “fuzz” in the water as it passes through. You could also vacuum to “waste” one time if you have something strange in the water. If you still have problems, check out Home - www.pro-sourcecaribe.com

    8,000 gallon pool. Use HALF the jar of flocking agent.

    My filter sand is almost 10 years old. I use the clarifier and algaecide about every two weeks unless we have had a lot of rain then I add more plus an extra chorine tablet. I backwash once a week or the next day after I've put in the clarifier. I don't have a filter problem.

    After you put the flock in and while the pool is on, it's a good idea to give your pool a good brushing.

    Sounds like the same problem I used to have with my pool water, it was clean but never "clean" and always a chalky residue would settle on the bottom. The problem was from too much phosphate in the water, have your water checked for that, if high use a phosphate remover as per instructions and be sure to vacuum to waste.
    Good luck!

    If it's brown, it's African dust. Finer than the finest jeweler's rouge. It comes over at 40-60,000 feet altitude. I used to scavange it from my boat's water filters to use as a polishing agent.

    Suck it up through a bypass to a 1 mic filter, let the filter dry, scrape it off, package it and sell it to auto paint shops.

    I agree that this is "African Dust". When it settles to the bottom, I vacuum to waste to get rid of it. I find no reason to use any chemicals, since it settles to the bottom by itself. A sand filter is not able to capture this fine dust. I am not sure even a DE filter could capture it.
