my sister had a 29gal. reef she was trying to get everything right in, but it really never happened. (bless her little heart). but she finally gave up on it and asked me to trade her a bare 55gal. i had sitting around for it, so i did. it is going to go through a small cycle so all the "critters" are in our other tanks and we get to start new on this one. i saved all the water and sand and rock, but the rock is all now in the other tanks, so it will be like a fresh start for the tank, i think the only problem when she had it was not enough lighting, and she couldn't afford a good reef light system ( gonna have a baby). any ideas on what to use this tank for ??
