    Can't get rid of cloudy water

    Hi -
    This is my first post, but I've been trying to follow the system since May. We've had a lot of rain here and I had a lot of pollen in June. About three weeks ago, I tried to vacuum up the pollen (thought it might be dead algea, but have changed my mind) and noticed it was coming right back into the pool (the cartridge filters weren't catching it). This left the water cloudy and I haven't been able to clear it since. The first thing I did to try to clear it was buy flocculant (thinking it was a clarifier). I followed the instructions, but it didn't seem to make the pieces big enough for the filters to catch. I then tried a clarifier which seemed to make it even more cloudy. I replaced the cartridges - didn't make a difference. I've had the filter running nonstop for the last two weeks. There was a slight change about a 5 days ago where it was still cloudy but I could actually see the bottom. There wasn't a lot there, but I vacuumed it anyhow. I've been brushing it every couple days. I bought a filter sock a few days ago, but don't notice any real difference. I've tried keeping the numbers in line (with the exception of running the chlorine high just in case there was any algea). Had a huge downpour Sunday and afterwards ph was over 8. Yesterday I couldn't see the bottom again. I was in a hurry so just dumped a gallon of muriatic acid in yesterday which is why the ph is so low today. Is it safe to swim in? Why so cloudy and how do I get rid of it?
    Thanks for any help.

    Welcome to TFP! Sounds like you are doing a pretty good job maintaining your pool!

    It is safe to swim when
    PH is 7.2 to 7.8
    Chlorine is between minimum and shock level for your CYA

    The water is clear

    As for cloudiness the best way to clear that is to Pool School - SLAM - Shock Level And Maintain your pool.

    Hi, welcome to TFP! I think in your case the filtration is the problem. Do you have pool vacuum that hooks up to a water faucet or does it plug into the skimmer? Have you tried using a better quality cartridge in your filter? You can get something like this : Pleatco PC7-120 Filter Cartridge - Intex Type : Swimming Pool Cartridge Filter Inserts : Patio, Lawn Garden which will filter better than the paper intex cartridges.
