Hi everyone/ anyone. Im new to here and new to pools. I started off light with an intex ultra 16' x 48" . I bought a Krystal clear saltwater system for it. That said the book keeps stressing when not to add cyanuric acid but says it is a must have in my pool. So when do I put it in? I'm just now done filling the pool after three weeks of leveling a two feet slope over twenty feet of hard georgia clay and building retaining walls. I'm ready to fly or fall. The instructions to the filter pump and the saltwater system dont seem to be enough for me Anybody have advice? Please!!?
