I have a jbj 28 gallon w/ 150 watt metal hilides, I had to get a nano chiller to keep it cool. Other than that its been running for about two months & I have 6 small mushrooms, a purple kenya tree, an fuzzy blue staghorn acropora, a feather duster, a bulb tip anenome, lettuce sea slug, sexy amenome shrimp, various crabs & snails, damselfish & everything is doing great. The tank is really easy to service, the only thing is the area where the powerheads & filter basket, well to put it frankly, there a little tight unless you weigh about 100 pounds.
