New pool owner here just bought the houses last winter and have been trying to learn everything I can about my pool, as this is my first experience with a pool. I have since switched to the BBB method after getting pool stored to death already. The pool is approx 13000 gallons and is an above ground vinyl liner. I have a 48 sq ft de filter and a hayward single speed 1.5 hp pump. So here is the problem, about a month ago I went to the pool store to have my water tested, this was before switching to the bbb method, they told me I need to shock my pool again and that my ph was low and that I needed to add a whole **** load of soda ash. no warning or anything. I believe it was 10 lbs of soda ash. They had me add it all at once at the same time I shocked it. Following this I noticed that my pool started to change color a little bit, and I didnt think much of it. Until the next morning My pool looked horrible. Everything was brown and just looked terrible. However the water was still clear. I headed back to the pool store and the told me it was obviously an algae. So they sold me more shock to shock the heck out of it and copper algaecide. neither of these processes had positive results. that is when i started doing some more research online and had come to the conclusion that it as a metal stain, which we do have well water so its not unheard of. and somehow the previous pool owners had never had a problem in the previous 10 years. So back to the pool store i went and got 5 lbs of glb stain magnet and some sequasol. dumped the stain magnet in and I watched the stains disappear before my eyes. I was relieved and thought that i had beaten the problem. added the sequasol to help sequester the metal. days later did a complete refresh on the de filter. 2 days later the stains started to reappear again. so i went back and repurchased the same stuff and hit it again and it looked great, again. well now the stains seem to be starting to reappear and i am defeated, i don't know what to do. and i cannot keep purchasing 100+ in extraneous chemicals each week. as of now these are my levels.
