Hi @Watermom!!

I just wanted to say that I have seen this warning a lot (in various context, not just from you) and I have to say that TriChlor pucks have never had any substantial effect on my pH. Now my pool water normally likes to rise in pH, I have an SWCG and a gunite pool so all those factors probably contribute to trichlor' lack of effect on my pH. Also, trichlor tabs take forever to dissolve in a float for me (typically 10-14 days for three 3" tablets to fully dissolve) so while the water locally around the float might be low pH, my pool water pH barely moves.

Truth be told, I rarely use pucks (only when my CYA needs to be bumped up) so I'm not regularly exposing my pool to trichlor.

Just thought I'd share my thoughts on the subject....
