I only use liquid chlorine to treat my plaster in-ground pool, EXCEPT when on vacations or away for a few day, then tablets. I have not drained my pool for 5 or 6 years, and the CYA has creeped up to around 100 (not sure need to test more accurately only on test strip), but I know it is high as despite FC levels high, I started to have a lot of algae problems at the end of this season.
If CYA is around 100, a half drain and refill should bring it down to 50. However, since I have not drained in over 6 years of so, is there any benefit to a complete drain (trying to save money in drought ridden CA).? Any other benefits or things that could be done at a complete drain?
Thx
Joe
