This is for the 25g that's been up and running for about 2.5 yrs. It has a CSS protein skimmer, power filter for carbon and flow, 1 koralia nano, 1 maxijet power head w/ hydor flo rotating deflector, and a 2 little fishies phosban reactor with another small powerhead. Right now it has pc lighting but i'm upgrading it to a 150w halide. It is a deep tank with about 35 lbs live rock, so there are many areas with varying levels of both lighting and flow. I do 15% water changes every other week. Tank inhabitants are 2 ocellaris clowns, one sixline wrasse, and one algea blenny. I also have a decent cleanup crew and a cleaner shrimp.
