This is my 180 gallon reef tank with a 125 gallon sump. The tank is almost two years old and doing great. I have four tangs and 16 mixed cromis, one lawnmower blennie, one diamond goby, two clown fish, two cardnals and lots of crabs and snails. Tank hardware is , two Euro-Reef RS-250 skimmers, one Geo 6-18 calcium reactor controlled by a litermeter III dosing pump and Reef-fanatic PH controller. one Geo Kalkwasser Reactor controlled by a litermeter III dosing pump. two Precision Marine media reactors one has GFO in it and one has carbon in it. one JBJ arctica 1/3 HP chiller, my lighting system is a Current fixture with three 250watt Metal Halide HQI double end bulbs, 8 T5 bulbs and 24 leds for night lights. My return pump is a Mag 18. Two powerheads in display tank are Hydor Koralia Magnum 7's controlled by a Red sea wavemaker. Refugium is 50 gallons with 50 pounds of live rock rubble and lots of macro algae, the refugium has a 96watt 65K light fixture above it. I monitor the Display tank and sump PH with two Pinpoint PH monitors. I have two large back-up battery systems for the reef tank there cyber-power 1500avr's one will run the return pump for 5 to 7 hours and the other one wil run the heaters and powerheads for 8 to 10 hours. Well this is most of the stuff in my reef tank, Thanks.
