Scuba tanks are not in ci, they are in cf... so an al80 is an 80 cubic foot volume of air when full. Depending on your paintball tanks, they run from 5 - 12 cubic feet of air each. Using the calculator I posted the link to, you will see you will only get a few fills about 2000 with a single scuba tank. But it's a start and better than nothing.
