My current tank is a reef ready 40 gallon breeder with a 20 gallon song sump/refugium. For filtration I run a SWC 160 cones skimmer, refugium and media reactor. Flow is provided by a MP40 with battery back up. Lighting is a myriad of L.E.D. units including: A.I. module, 36" 50/50 reefbrite, 2-24" actinic reefbrites, Par 38, 15" 50/50 Reefbrite. To control it all I use a Reef Keeper which also runs my dosing system.
