On my 225 gal. reef I have a 55 gal sump with 40lbs of sand and rock rubble, a Euro-Reef CS8-2 skimmer, 4 filter socks, a 2000 gal/hour main drive pump that feeds a 30 gal refugium (abouve tank) and a thirty gal Carlson Surge tank that drains evey 1min 47sec., and a diy calcium reactor. I also have 2 650 gal/hour Mag Drives inside the tank for ciculation. I know I'm forgetting something. I'll take a look when I get home.
im alittle dissapointed in myself for not thinking that up myself (thou it is sunday morning and i havent had any coffee yet)
