I'm up and running and with all the rain we've had in the spring here in the Northeast, my CYA is all but gone. I had 1/2 of a 5lb CYA jar and a 8# jar of tri-chlor pucks from last year so I thought I'd go through those to raise the CYA back up (I run ~50ppm).

I threw the CYA in a stocking, tied the end and threw it in the skimmer last night. To my surprise, it was all gone in the morning. TOok another CYA reading and there's been no significant change.

So... where did the CYA go? Did it dissolve or simply disperse and is stuck in the DE inside the filter?
