steve Tyree basicly uses live rock in an unlit sump for his natural filtration method. has anyone else tryed this method? I recently switched from a refugium to this method , and im not sure what to expect. also how long does it take to become active, I know it takes time for sponges and other things to grow on the rock, but how long can I expect before its at full potential.
also my live rock dosen't really have anything growing on it, should I buy a small package of fresh live rock to seed the other rock?
