I have successfully cleared my pool, I Don't have my numbers with me at the moment from test kit as im at work, but i know everything is slightly high, except for the pH it's perfect. When I say slightly high, I mean just barely over recomended levels. Here is a pic of my pool, can anyone tell me what the stains are? This is the only good pic I have currently of the stains, I can zoom in tonight and submit more if requested. I am trying to scrub them with no success. I think the black stains are algae, they are slimy I scrub them and they become dry feeling. The pool was a swamp for 6 months to a year before i started working on it. Thanks.
Also, I have a yellow looking stain on the steps, pool walls and bottom. I think its yellow algae? I scrub and scrub and it wont come up. Any ideas/suggestion would be greatly appreciated.
