Hi folks:
We opened up our pool today. 32K gallon Gunite, inground.
I was pleased to see the water was pretty clear when we pulled back the LoopLock cover. Much much much cleaner than the green swamp we had last year when we opened!
Overall the pool looks great and I've started my SLAM. EXCEPT...there is a large, dark / blackish stain on the floor adjacent to my floor drain. It looks as if something (leaves, other debris) was stuck there over winter. The debris is gone but the stain is unsightly.
I've tried scrubbing in for minutes with my plastic brush on the end of the pole. I've driven my Dolphin M500 robot back and forth over it a dozen times. It seems a "bit" better but is still there.
Suggestions on how to get rid of it without having to drain the pool? Pool chemistry is ok. PH is too high, and CH a tiny bit low. Otherwise all is good.
Thanks!
