CO2 tanks
Has anyone tried using paintball tanks for their aquariums? I have been
considering making the jump to a pressurized system but want to spend
as little cash as possible (and still have a system worth having). It
looks like I could buy a used 20oz. paintball CO2 tank for dirt cheap!
Would this run out to fast? Are the threads compatible with
regulators/valves that are appropriate for aquarium use?
