I am still setting mine up...I've got two Coralvue 150/175 Electronic ballasts for MH bulbs, and a PFO dual VHO ballast for actinics. I've built a sump out of a 15 gallon tall, and I am running the promo Euroreef 80 from Premiumaquatics. Two 125 Watt Ebo jager heaters, return is a Mag 9.5 going through a SCWD and I've got two Maxi Jet 900s for some additional flow in the tank. My main intent is clams and whatever lps or softies that can handle the lighting.
