I don’t have no big fancy set ups. I got country ingenuity. I decided to try and lower my TA some more and the is my way of aerating. The best $80 I’ve ever spent was 6 years ago on this little pump from Lowe’s. I hook a hose to it and move the water in any direction. I can just blast water to the sky. Now I found an in-line sediment filter I thought I’d try out. Most of the water was trucked in but there’s enough well water in it the the iron from it does discolor my calcium test. I think it looks purple before it turns blue. Husband says it’s red. Anyway I’d like to get the iron out. I’m gone buy this thing and hook it to my little pump and filter the pool. See if it works.
