I've finally gotten my CYA level up to 33. My questions now are these: 1. What is a healthy level of CYA to maintain? 2. Does stablizer disintigrate on its own if I stop using dichlor and only use bleach? 3. Once I reach that healthy level, should I switch back to only using bleach, or maybe bleach 5 days out of the week and dichlor the other 2?
