I saw the tanks that Steve built, I believe this is one of the best cube tank out there. I wish I have one like this. I am into cube tank, and this is really the best one I have see in person. If Steve can built another one like this in glass then I would love to have one. *hint hint* You gotta see it in person to see how nice it's. The overflow is really clean and all flow into the back. The drain pumps is really silent, you hear no water falling down to the sump. Nice job Steve, if you ever have free time and want to experient to built want with glass I would love to let you built me one :-) I will pay for all the matterials, parts and labors :-)
