Cali, I always understood that kalk drip without a calcium reactor was not a good choice for alk/calcium maintenance. Doug at Deltec talked me out of a kalk reactor and told me to use 2-Part instead. He said that on an SPS tank (without a calcium reactor) it would cause honeycomb and brittle corals.
I read a discussion on RC between Doug and Randy Holmes Farley on Doug's theory on honeycomb and brittle corals using only a kalk drip.
In a nutshell, Doug was wrong
