Thread: cloudy after shock

    cloudy after shock

    First time pool owner and learning the ropes. Everything was going smooth until I went on vacation. I returned to a green swamp. I initially used strips which showed FC 0 and CYA 0. I corrected ph, then added cya and shocked with bleach until FC continued to read high on strip overnight. Water changed from green to blueish but is still cloudy. Frustrated I called a friend and long term pool owner and he recommended the BBB method and TFP. Great site with lots of info and fantastic pool school. After 5 days of cloudy water, I ordered a real test kit. FC stable overnight and no CC, but still cloudy. These are my most recent numbers,
    Ph 7.5
    FC 14
    CC 0
    TA 80
    CH 70
    CYA 40

    I dont see in algae or green areas, but I can only see bottom in shallow end as pool continues to be cloudy. What do I do next???
    Thanks

    You've done well grasshopper! Welcome to TFP.

    Have you read about adding a little DE to your sand filter?

    Re: cloudy after shock

    i have read the section, but had been thinking the sand filter would just take longer to clear the dead algae. However after initial daily improvement, now it is minimal. I have been backwashing 1 or 2 times per day. How long is needed typically for sand filter to clear? Or do I just need to add the DE since it has been 1 week?

    Since it's been a week, I'd add about 2 cups of DE to it and see what happens. Watch the pressure when you do because it may climb pretty fast.

    Your choice to add DE or wait. My guess is either will work, you just have to decide how much patience you have.

    You may be backwashing too often. You only need to do it when the pressure rises 20-25% over the clean pressure. As the filter gets dirtier, it will catch smaller particles, but if you wait too long, the flow is reduced too much.

    pool is beginning to clear, I can see the bottom in the deep end. Cl levels stable. Thanks so much, looks like I just needed a litle patience.
