We are relatively new pool owners! In ground, 24,000 gal, DE filter, non heated pool. We use Chlorox and muratic acid and pretty much nothing else to run our pool. We run a high cyanuric pool (80+). But from this site I have learned that I can run a high CL pool to balance it. This site has been a great place to help me overcome my apprehension of running a clean pool. I no longer buy any chemicals at the pool store. Every once and a while I get stumped and need some help so I look forward to having y'all's help! MKb
