Direction Question

[Chriscrna]

I use Red Sea Coral Pro. Haven't checked the levels in a fresh mix in a long time. Granted I'm only changing 10% every 2 weeks, but I've never had a change in my alk. Along with a doser, alk stays rock solid at 9.

I'll do a water change in a couple days. I'll check a fresh mix alk at 1.026 and report.
