Well im going to be drilling my 55 and hopefully it's not tempered lol.. Well my other problem is the stand it came with.. Not very big and theres a big divider in the middle.. Almost like its 2 halfs.. I was thinking about puttin 2 10gallon tanks in the stand.. 1 on each side of the divider and drill a hole through the divider and plumb the 2 tanks together.. 1 for a sump and 1 for a refug.. My question is how could I do this? Should I get a small pump and pump from 1 10g to the other and then back up to the main tank? Any info/pics/suggestions would be great! Im gettin my bulkheads and hole saw tomorrow..
