All,I have a brand new pool, like 60 days old. After about 5 weeks I started getting these brown spots all over the pool. I have no grass around the pool so it’s not from fertilizer. There are about 300 of them of various shades.
Initially my pool builder said black algae but it’s clearly not algae. My pool guy put a double dose of Algecide in the pool with no change. My pool is maintaining its chlorine which also makes me confident it’s not black algae.
I have had the water tested for everything Ph, calcium, metals and all are perfect. The water is excellent but these spots keep popping up.
I’ve tried muratic acid, lemon, scrubbing, letting shock sit on the spot (actually thankful that didn’t work because it wouldn’t be feasible to do that 300 times)
I have attached pics, any suggestions are appreciated
