Good day all!
I've been a long time lurker and created an account a few months ago to use my TF test kit with. That was a great recommendation that I read from this board, so thank you for that.
This is my first post. I've been struggling with keeping the bottom of my pool clean for the last 3 weeks or so. We opened it in late May, and after initial opening, the pool bottom had stayed pretty clean consistently through the summer until about 3 weeks ago. I'd probably vacuum it twice a week, tops, and even then it wasn't too bad.
However, as of the last three weeks or so, I'm vacuuming it every single day, and every single day (the next day, usually), it's filthy again...long dark streaks on the bottom of the pool that appears a brownish/yellowish color...more dark than yellow I'd say though. It also "sticks" pretty good so I have to go over it several times (slowly, of course) with my manual vacuum to get it "cleaned"....but alas, a few hours later, it starts to show up again, and the next day, it really starts to build up to a very noticible amount, so I have to vacuum it again...and rinse/repeat for the last 3 weeks...It's getting quite frustrating.
This exact problem occurred last year around this same exact time---pool mostly clean June through early August...then filthy. There are some trees around my pool but nothing that is blowing anything but small bits of leaves and what not---things that are obviously from trees, and those vacuum up just fine. But the brownish looking "residue" that I'm talking about here is the problem.
I do use a heater (heat pump) and a solar cover (maybe the cover is constantly dirty?)....but I've tried cleaning and replacing the solar cover daily...and the bottom is still dirty....and I've tried cleaning and leaving the cover off for a few days, and the bottom of the pool is still dirty. So I don't think it has anything to do with the cover, nor the trees around my yard.
I test the chemistry a few times a week and all the numbers are always good--and if they are slighly "not good" I adjust immediately. As of my last reading, here's my chemistry:
PH = 7.6
Alk = 70
CYA = 50
FC = 7.0
CC = 0
Hardness = 200
It's a 21 foot above ground, roughly 11,000 gallons. In Maine. The only thing I can think of is that whatever I'm cleaning is just returning back into the pool through the sand filter. There is one return jet. BUT, I've also tried vacuuming to waste and the problem just keeps coming back. Is it possible that the filter is not working at all, or that it is broken and returning debris into my pool? It's only 1.5 years old, as is the rest of my pool set up.
Or, is it possible it's some kind of algae (mustard perhaps) even though I've kept FC high enough per the CYA levels all summer long consistently? And the CC is 0? Could it be pollen that just blows in every day and is just something I have to deal with?
Sorry for the long post! TLDR: Bottom of my pool is always dirty, I clean it every day, and the same brown/yellow streaks show up in the same places every day. Chemistry I think is OK.
