We'll try to help you, but there is some basic information we need first. Please take a sample of your water to a pool store and have them test it, and post results here for TC, FC, pH, TA, CYA, and any metal content. Don't let them talk you into buying ANYTHING. For help clearing up problems, the test strips simply aren't accurate enough. Post some drop-based numbers up, and we can go from there.
