So I just left the nearest Namco branch annoyed. I've run out of CYA. No CYA, not Tri-Chlor, no Di-Chlor. So I went there and do they have CYA? No. They have "Stabilizer and Conditioner". What's that? Why it's Cyunaric Acid AND Sodium Carbonate. No Stabilizer. No 100% CYA.

They've mixed CYA with Soda Ash, clearly because Soda Ash is a cheaper product, but raises both pH and Total alkalinity. My pH is perfect, my TA is perfect. I haven't seen my pH change in 6 weeks!

Very frustrating.
