jmitch7417 Posted October 16, 2016 Share Posted October 16, 2016 I just picked up a 40B of a local reef site. It currently has a black box. After I get rock and sand in it I plan on changing out the light. Will one Kassil 350 work? or Will I need 2? Also how much rock are you guys running with these tanks, and sand?

hooligan76 Posted October 18, 2016 Share Posted October 18, 2016 Rock should be around 1-1.5lbs per gallon so 40-60lbs for a 40B tank. Sand is kind of a personal choice some like a shallow bed some deeper, I keep mine about 1.5" deep, if you have some Wrasse that bury in the sand bed to sleep a little deeper may be needed. I would say two Kessils for a tank that wide, one probably won't give you the spread you need. Two 160's would probably work for you & be a more cost effective than two of the 360's unless you're going full SPS and need the extra power. Link to comment
