Well I couldn't hold off until I got my larger tank up and running, so I went and purchased a 20 gallon long and 10 gallon (for fuge/sump) and am now needing some equipment. Looking at getting this up and running fairly cheaply, so I can concentrate on getting the good equipment for the larger tank. What I need is:

Return pump (nothing large, this is only a 20 gallon tank, but enough to make a 30x turnover ratio - 700 gph or so)

Need to drill a hole for an overflow - can anyone point me in the direction where I can find a good diamond tipped hole saws? Hole will need to be either 1-1/8" (1/2" bulkhead) or 1-5/8" (3/4" bulkhead)

Lighting - looking at either PC or T-5 (from 20" - 30" in length)

Thanks
