In your opinion, is there a true difference in the power of calcium provided to the reef systems? Would corals grow differently or be affected from one versus the other?
I'm trying to make the decision to purchase a calcium reactor or start blindly adding kalkwasser to my ato water to refill the tank?
In my experience, the kalkwasser addition did the trick because I've always have stony corals in my systems. Currently I have a 40g breeder with a a few larger colonies of sps corals.
Please let me know your thoughts/opinions.
Larry.
