Retested CYA at 40. Probably didn't wait long enough after the addition for it to show on test last time. FC is still dropping. Topping that up to 16 ppm 3-4 times per day as time allows. Only dropping down to 13-14 ppm range between adds. CC is pretty steady at 1.5
I don't test CC every time, but checked 2 days ago and again today. I realize I don't NEED to, but again, that analyst instinct gets me every time. Thanks for making sure I knew though.
Ok, after seeing the pics side by side I now can tell today's improvement was better than I thought.
