I think 03Mach said he had some deck screws, which would be best because they are corrosion resistant, I will be bringing some other screws that would work, but may corrode.
I have plain old window scrapers/razors that should work just fine on the back of the tank.
Antoher main thing will be dealing with the floor/leveling it. Hopefully we can get away with just shims.
I'll be bringing a circular saw, extensions, level, various tools/hardware, cordless drills , drop light, fan, and a shop Vac if it fits in my car. Also a plain old hack saw which should be fine for cutting PVC.
