I used tablets for years. After battling algae problems, I found this wonderful site and learned about CYA. I drained my 27K gallon pool and restarted spring 2019. All went well last summer. At the start of this season, I checked CYA and it was low. Since I was out of CYA proper, I thought, "what the heck, I'll just use tablets until the CYA level is where I want it." Used 6 pucks. No change in CYA. 8 more. No change. CYA is something like 30-35 (hard to tell when the black dot disappears).
I don't think its a CYA measurement problem, because chlorine consumption (with new, just bought chlorine) us more than 2x what it was this time last year.
Is it possible that those tablets (from Leslies) don't have CYA? It doesn't list CYA on the label (see attached).
Thanks SO much,
Paul Zimmer
