I was actually more concerned about the PH swing. I drip 1 gallon at a time, dosing my normal amount of 1 TSP per gallon. The tank is a low cal demand tank, I have a 2.5" Crocea and 2.5" Maxima clam. I also have 4 small SPS frags and a few smallish LPS frags. The most of my corals in there are Zoa's and a few softys. I also have a bit of a Macro collection.
