Hello All, As far as equipment goes, I am running a Pro Clear Pro 75 trickle filter filled with bio balls and live rock in the sump,a built in Pro Clear 75 skimmer,up top I have an Emporer 280 filter mainly just for circulation and to catch some of the debris, 2 Koralia 2 fans and a Rio 800 power head,lighting consists of 2 30" 130 watt Coralife power compacts. As far as inhabitants....Mated pair of Clarkki's, 2 spotted cardinals,long spine urchin, a brittle star and various corals. We mainly would like to stay with coral though for the most part.
