So through my tests I have discovered that my CYA is 100+, all due to trichlor. I have turned off my chlorine feeder and removed the remainder of the trichlor tabs. I have dropped my pool water to an inch or two below the skimmer once and brought it back up in attempt to get CYA to good normal range. Couple questions
When I retest the CYA, should I have the pump/filter running for a bit to mix the new and old water?
How long should I wait after adding new water to test CYA?
Is there any hope that I will be able to swim in my pool this weekend, or ever this summer?
