Hello TFP! Thanks for having me.
I just moved into a new house, and it has a 13,000 gal pool. I've never had a pool before.
I've balanced the water, and it is crystal clear.
However, I have these green/yellow stains that I just can't get rid of. They are around the main drain.
They are pretty substantial in size. About 2-2.5 feet ALL THE WAY AROUND THE DRAIN. I've been scrubbing it with my pole brush, and it seems to get a little lighter in color, but, it looks terrible. What can I do?
Thanks for any advice. I'm all ears !
