    White Residue and slimy water

    Hi, I have an inground salt water pool. Had algae and shocked pool, went away on vacation and now a white residue on bottom of pool when brushed looks like a cloud. I assume this is the dead algae? I can't get rid of it. When I vacuum, pull vacuum out of pool and see a cloud so it's going right back into pool.

    That is my first problem. Second, pressure is high on Hayward filter, constantly 20, where in past would be 10. After backwash right up to 20 again.

    I looked over some forums and thinking I should clean the grids in the filter but should I take care of the white algae first?

    Here are my readings:
    FC: 3.2
    CC: 0
    PH: 7.6/7.8
    TA: 80
    CH: 190
    CYA: 80

    Water is clear.

    Thanks for any help.

    If it is blowing back into the pool, sounds like a lateral might be broken -or- the particles are too fine to be stopped by the sand. Maybe add a little DE to help strain the finer stuff...

    Thanks for such a quick response.

    It's a salt water pool. I did add DE at last backwash.

    When I pull the vacuum out it is the type that crawls around on bottom of pool and has to be lifted out of the water and that's where I see the cloud.

    Oh so its coming out of the vacuum itself? Maybe the filter system in there is clogged.. Not really up to speed on robots.. maybe its gathering the contaminants but not letting them into the pool filter.. have you tried swimming with it to see if its working correctly underwater?

    Your problems are the same. Your hayward filter is doing what it is supposed to do.....filtering debris out of your water. You must keep continue to backwash over and over until all the debris is removed. Same for the robot. It is trying to remove debris from your pool and is simply getting so full some of that debris overflows when you lift it from the water......they all do that.

    You must continue to brush, run the robot and run your Hayward filter 24/7 until your pool clears.

    Thank you duraleigh.

    I will continue to brush and backwash (approximately how many times a day?). I will turn the filter on 24/7 tonight.

    So there isn't a need to take the filter apart to clean the grids? Is there any need to add chlorox/bleach do you think?

    Thanks so much.
