My pool was down to 35 ppm cya. good.
But I wanted it to be closer to 45-50 max (pool gets full sun every day) so that it would use a little less chlorine each day.
I put 3 leftover trichlor tabs in and they dissolved in a week.
Then I put 4 more in and dissolved.
I tested CYA recently and now its 80ppm.
For a 23,000 gallon pool are the trichlor pucks 6ppm cya each? sure seems like it.
I guess I should have tested after the first 3.
