Well the 210 is already running. I never really totally brpke it down. I have ~400+ lbs rock, 300 in the MD and 100 in the sump (40 gallon with a homemmade breakwall) I have a 4` coralife with 2x150 HQI and 2X96 actinics....yea...Iknow, very underpowered. But is is better than nothing. Im looking fro 2 3` T5s now. Also Im looking to replace my PM bullet 2 with a different skimmer....a long story but the bullet dowsnt fit where I want it to go....I have just added a couple pieces of softies, 1 toadstool and 1 colt for now and things look really good. The tank just had the closed loop running for months and the rock Cooked, in the dark basement so there is not a sign of algea.
