Aeration raises pH without raising Total Alkalinity, unlike other means of raising pH. That is its purpose.

Why would the CYA in Tri-Chlor be "inferior" to straight CYA? CYA is CYA. I have no problem with using Tri-chlor to raise CYA, when at the same time pH is high, because Tri-chlor will lower pH as well.

I swear I read that somewhere . . . realizing it doesn't make any sense and that cya should be cya, whatever the source. I'm sure I read that on this board, back before the meltdown . . . I'm sure it was just someone's opinion . . . like everything else . . .

I agree with CarlD. Just add a little straight cya and don't fool with the trichlor. The good part of just adding cya is that after a week or two of tweaking it, you will seldom need to test the cya level again - maybe only a time or two during the entire swim season. When using trichlor, you have to continually be checking the cya level because it will quickly climb and without realizing it, your level will be too high. I always just add the cya and forget about it. Too easy. Easy is good!
