I have just begun setting up my Intex 15' x 48". It came with the Krystal clear 1000 Gph filter pump. I had my water tested and there is copper in it, so I know I need iron out, and it was suggested I use conditioner and chlorine stabilizer. Besides chlorine granular I have is there anything else I need to put in? Also after the directions for the filter, there is a picture for a dual Chanel, but no directions and it is not included in the DVD. There is enough pieces to do it, I just don't understand why the DVD for this specific filter (1000 Gph) doesn't even mention it?
