Just an update, after small water changes to the tune of about 40% over the past week the levels in my tank are starting to return to normal, accept ph. Calcium is rising from 160ppm to about 300ppm as of last night, and Alk is dropping from about 10 Meq/L to around 6.5 to 7 again.
I can't seem to get my Ph back in check, as of last night it sits at around 8.8 even after all the water changes. What can I do to drop this down without adding CaCO2, which also seems to boost my Alk levels? Some of the corals are picking up but I did loose my long time BTA, poor clownfish, thankfully he has the RBTA to fall back on.
