I am really interested in the possibility of rearing larvae from some friends reef systems. I undersand the issue with saltwater is breeding is mainly getting pelagic fry to survive, and was wondering how to set up a Kreisel Tank to replicate a pelagic environment. What is the smallest I should go, I am thinking either a 10 or 29 gallon what sort of filtration would it require, should/can it be set up as a stand alone, or should it be connected to a larger saltwater system.
