I have a relatively new pool and I have already seen the light. My CH is at 350. I’ve been asking the pool store why it is rising and they don’t know. Well after reading here I do. It’s from the shock they sold me. I’m going to start using bleach and I have a few questions. First, I bought a huge tub of tabs for my inline feeder. Can I keep using those until I run out? My CYA is 50. Second, do I just buy bleach and put it straight into the pool as needed using pool math? Lastly, do I need to drain and replace water or will I be ok as long as it doesn’t keep rising? Thanks!
