Hello everyone,
I am going to be upgrading the equipment for my 75 gallon aquarium over the next few months and wanted to get some input on co2 regulators. I am currently using a single stage paintball co2 regulator and it works well, doesn't empty the tank at the end like some of the other regulators do. My main question however is, is there a difference between using a full size regulator vs a paintball regulator?? I own a full size regulator as well, but have had problems locating a 10-20# co2 tank, and all the stores in my area do an exchange, so I would end up buying a tank and then giving it away for a used one. So I was thinking of just stocking up on smaller paintball co2 tanks and just have back ups ready when they empty out so I don't have to worry about running out, and I can keep some filled on hand just in case the store runs out, which happens pretty often. If theres no major difference in the regulators I will probably upgrade to something like pictured below for my paintball set up. The second picture is of a regulator that looks almost exactly like my large style regulator.
