My CH level is continuing to creep up for some reason. About 6 weeks ago it was 280 and now it is around 350. In that time period other than adding bleach, muratic acid, and the occasional baking soda, I haven't added anything else. What is causing it to rise and how high is too high before I need to replace water. Also if I continue to add water due to evaporation, shouldn't this drop CH and CYA?
Thanks for any help.
