    Algae appears when filter runs

    Good morning, My main drain has been capped due to a leak so we're trying to limp by this summer before looking at options. I knew we'd have a rough summer fighting algae because of poor circulation, but this one I can't figure out. I always end up with algae this time of year when the sun...

    Build-up by returns, don't think it's algae

    Hi all, I seem to have a build-up of tan/white clumps under the returns in the pool. I don't lose any chlorine overnight, CC is 0, and it's nowhere else in the pool. When I brush, it "poofs" away and dissipates. The rest of the pool is clear and nothing is kicked up when I brush. We replaced...

    HELP - valve stuck & laterals pulled out

    I started a new thread because we created a new, huge problem. We tried to remove the valve to inspect for debris or cracks, and the valve is stuck on the pipe inside the sand filter so tightly that a slight lift pulled the laterals up. Now that the laterals are all messed up, we've been trying...

    Losing water & possible sand filter pressure leak

    We have a lot of issues with our pool that I think (hope) are related: 1. We've been losing about 1/2 inch water a day. This happened last summer too, we dug up the pool lines we could access and had someone check for leaks in the pool. Couldn't find anything substantial. 2. When the pump turns...

    Constant Algae that won't die

    Hi all, I've been SLAMming pretty much since we opened the pool at the end of May here in NJ. We had about a week after I passed the SLAM tests, kept the FC within the range, etc. Then we got a few super hot days here and the algae came back. My FC had dropped too low one day while at work and...

    Pollen or Algae?

    Good morning! I've been SLAMming for 17 days :mad: I had ammonia, but was able to kick that quickly. My pool has been crystal clear for at least a week with the exception of small accumulations of what I believe is algae. I haven't done an overnight test because I keep thinking I have algae...

    Constant Uphill Battle

    Hello all, We have been in a constant uphill battle with algae blooms. We have direct sunlight all day and the pool stays at about 86, and it's difficult to maintain FC levels, but we always keep it above the min (or it only dips below briefly, because ive been having to check it morning and...

    Going on vacation for 5 days

    I will be going on vacation for 5 days. With a CYA of 40 and direct sun for most of the day, I'm currently adding half a bottle of bleach every day or two. I will be gone for 5 days without anyone to care for the pool, and no cover. If I bring the pool up to shock level, will it be OK for the 5...

    Cannot get FC level to rise in green pool

    Hello, we bought a house last month with a 22k gal inground pool. Vinyl lining, sand filter, everything relatively (within last 5 years) new. The pool was not professionally closed. We opened the pool Thursday 5/26 and the water was clear but bottom was green. We shocked the pool as directed...
