    Water problems

    I've been slamming my pool for about a week now and although I have cleared the water up my water is still cloudy. Cya is at 40 so I'm using 16 as my chlorine shock level according to the cya/chlorine chart. When I started slamming I had a combined chlorine of 1 and I did get that down to 0. Any help would be greatly appreciated.

    Fc 16
    Cc 0
    Cya 40
    Ta 70
    Ph 7.4
    Ch 100

    Re: Water problems

    At this point we might ask the following questions related to your SLAM:
    - Have you been backwashing consistently when the pressure increases to 25%?
    - Scrubbing/sweeping daily - as much as possible each day?
    - Pump running 24/7?
    - When was the last time (if ever) your filter was deep cleaned?
    - Ladder removed and cleaned; even inside each ladder rung?
    - Do you have a light fixture perhaps that could hold algae behind it?

    From there, assuming you've been doing all the items on the SLAM page consistently, it may still boil-down to time. Perhaps adding a little DE to your sand filter. I say perhaps because I would leave that as a last option only after ensuring everything else has been maintained. Normally we leave the OCLT for last, but I'm curious .. have you tried one yet?

    - - - Updated - - -

    The only other thing I can think of .... CYA. Just make sure (in good, bright daylight hours) that your CYA isn't actually higher that 40. If it was, then you may need a slightly higher SLAM level. But that's the only other thing that comes to mind at the moment.

    Re: Water problems

    You're probably at the point now where you might want to re-read the SLAM article. The last line, where it says, "If you have a sand filter..."

    Also, pull that ladder out and check it carefully. See the picture in Problem Found and Ideas needed

    Re: Water problems

    I have not pulled the ladder out so it looks like that is my next step. I have been back washing as frequently as needed. The pool is roughly 5 years old with Pentair sand dollar sd60 sand filter. Also I have been scrubbing morning and night and I've been vacuuming daily also.

    Ha ha . "Next step". I get it. Okay, bad pun. But that could be your culprit. You'd be amazed what those things can hide.

    Looks like the ladder is my culprit! As soon as I started removing it I could see the green cloud.

    Re: Water problems

    One more question since it was mentioned a couple times. By telling me to add DE to my sand filter I'm assuming you're meaning D.E. Filter powder but what brand would be recommended?

    Doesn't matter. See if any of the neighbors have any they'll let you have. You'll only need a few cups and the smallest package is a lifetime supply. Don't buy garden DE, even though it's in smaller packages. Not the same stuff. You might also see if a small bag of cellulose filter powder (Fiber Clear is one brand name) is cheaper, because you won't be using all that much. It's a DE substitute.

    Re: Water problems

    So after further investigation and cleaning the ladder thoroughly I followed the link of the last person who had an algae problem in their ballast. I opened up the footing of my ladder and boom I found more algae hidden! You people have been a tremendous help!
