Hey im a pretty new Sheridan reefer, and Tim told me to post on this site. Guess ill tell you guys what i have going on for a reef system. Starting from the top i am running 1 Marineland reef capable LED 24-36" on a 30 gal tank with about 90lbs sand and maybe 50-60 lbs live rock. I have a (half-full) 10 gal that i use as my sump, with about 10 lbs live sand and about 15 lbs reef rubble. For filtration i use a Marineland 4 stage C-220 inline with Livegard aquatics QL-15 UV sterilizer. My return pump is a quiteone 2200. well that's my setup and i'm glad i because join a local reef community :bigsmile:
