I have a 29. I have taken the hood off and put on a Sunpod 150 watt MH. I have widened the slot from chamber 1 to 2 and replaced the stock sump pump with a Rio 6hf.
I love the tank. I like the cube design and the all in one style, but to tell you the truth if I were doing it again I would buy an AGA and make it into an all in one myself.
