I’m considering switching to 2 part dosing on my 375 gallon mixed reef. I’ve used a calcium reactor for many years on my tanks, but I’ve been way overdosing on my calcium lately. The tank has some SPS, LPS and lots of softies. I’d like to hear options for dosing calcium and alkalinity. Any pros or cons I should consider. My 8x18 GEO reactor works just fine except for overshooting the calcium. I’d also like to see how the tank does with higher ph from not having the CO2 streaming in the water.
