We were away for a few days. When we got home, we found that a bunch of small (about 1 inch long) worms had decided to swim in our pool. We got a bunch of them out. But, it looks like a few died on the bottom and are now decomposing. So, we have these little raised brownish yellow circles on the bottom of our fiberglass pool.
I can't brush them loose. Somewhere I had read that scrubbing with a chlorine tablet would help....I tried, but no change.
Our water is nice and clear. We have a SWCG. CYA and calcium hardness are fine. pH never varies beyond 7.4 - 7.6.
There are about 5 of these stains spread around the bottom of the pool.
Any suggestions on what else to try?
