Just curious how many here use a Kalk reactor in addition to their Ca reactor.
I incorporated one on my system but pulled it off line after troubles. Its rather long story but short version, I had it being controlled (dosing times) by my APEX, and even at a single drip every 2 seconds or so, it was adding more water to my sump than was evaporating.
I added it merely to compliment the Ca reactor, as I read that was the best of both worlds.
I have PH around 8.10 at the peak of the light schedule and lows of 7.85. I have had these levels for nearly 16 months and my tanks is very healthy and growing corals very well too.
My tank is about 85% SPS.
Anyway just curious how many, if any, are doing both?
Questions to follow once I see the replies.
