OK my mentors...
1. I am buying some lights from Lowes today for the tanks. These are FOWLR. Lowes has NO florescent, and they have T-6's. I don't know what all this T stuff is (sorry...working on this physical science stuff I hate). I know T-5's are supposed to be great so...are T-6's at least better that NO? I'm sorry I'm such a dummy about this.
2. I have a student whose parents own a fairly major plumbing company. His dad gave him permission to go to the warehouse and get whatever I need to plumb the tanks, but I guess bulkheads are not something they have. Is there something else that is similar that I can get from them? Something that a typical plumbing supply company would have?
