Here is an update on the 75 Gallon Tank I added to my 180 as a sump. http://www.marinelifeweb.com/Tanks/sump.htm
I added a 75 gallon Reef ready as a sump on my 180. The tank gets the water from one of the sumps I already have and is feed from my chiller. Gravity then feeds the water back to the sump. I added Live Rock, Xenia corals, and caulerpa to the sump along with sand. I have a 250watt 6500kk MH
on one side and a 18W PC
on the other side. I am going to be changing out the PC
and go with another 250Watt MH
. I have about 250-300 pounds of Live rock in the tank, from Marshall Island, Kaelini tonga, Fiji, and one other that I forget were it was from. The total system is about 300 gallons with about 600 pounds or Live Rock. Sorry for the dirty glass.
