    Mustard Algae?

    Ok, I opened pool and it was green this year. So I changed sand in filter and did the SLAM to clear pool. It took about 8 days. It passed the over night test, water was clear, and CC was 0. Now water is still crystal clear. The problem I am having is when I clean pool the next day or so I start to see what looks like dirt on bottom of pool. When I brush pool it looks like it just poofs up and disappears. I brush pool, and vacuum bottom, but it comes back. I am at wits end trying to get rid of this dirt or algae. Any help would be appreciated.

    I doubt it's MA since MA typically lives on the side or bottom areas where there is shade. If you are able to pass an OCLT it probably isn't regular algae either. So perhaps what you have there is simply dust/dirt (or pollen) blowing-in from around your area. How does everything else around your property look? Any stuff settling on cars, patios, etc? Is your filter pressure changing excessively quick? Algae will do that as well. Do you use a skimmer sock on the poolside skimmer(s)?

    I have landscaping back by pool. I don't really see much pollen or dirt on anything. Filter pressure doesn't change much at all. It stays about 14 or so most of the time. Also, I don't have skimmer socks on my skimmers.

    Very possible that's just dirt from the area. If it was algae, you would not pass your OCLT. You might want to try some skimmer socks. Old nylons or 1 gal paint strainer netting over the skimmer. They also sell them on Amazon I believe and they catch a lot of junk before it goes to the filter. Also, try dropping a couple ping pong balls on the water and see how well your circulation is.

    Ok I will give the skimmer socks a try, and see about circulation.

    Any luck getting rid of you dust/dirt/algae from your pool. I am having the same problem, no amount of brushing or vacuuming or filtering will get rid of it, it just keeps coming back. My water passes the OCLT and is clear except for the dust/dirt on the bottom.

    Thanks,
