Moderator comment - Moved from here: CYA 152 Should I Add Optimize or Stablizer
After fighting high CYA for a year, we finally had so much rain, the pool was practically refilled. Right after the rains my CYA was around 40. On this weeks test it appears I have no CYA. Using the black dot test and did it three times. My pool is eating chlorine, I've been having to add a gallon every day this week (yes, it should have been a clue). Our pool temp is 95 degrees! I have a little algae in two corners, so I'm starting a slam. Should I add stabilizer first? Any preference to the brand of stabilizer?
Thank you in advance, I couldn't do this without everyone sharing their knowledge.
