Two years ago I bought my house with my first pool. I have high pH, high CYA (pool came that way), massive chlorine consumption, algae, dirt, and leaves in my pool. I know it's my fault, but I feel like I'm constantly working on it. Once in the morning, once after dinner and a good portion of Saturday mornings. I don't know how much more I can take.
My friend, on the other hand, doesn't have a test kit and just floats two tabs at a time and throws in a pound or two of shock every month and his pool looks great. How does that work? Shouldn't his CYA be through the roof? Wouldn't two pucks of trichlor (~12ppm Cl/wk) be almost worthless in a pool with very high CYA? I attribute all my issues to a domino affect setup by high CYA that I never fixed. Why hasn't his pool spiraled out of control like mine has?
