Sorry I'm sure this question been asked a million times but I finally came up with enough money for a pressurized co2 set-up and was wondering where are the best sites to get this stuff that people have good feed back on. I will be using on more than 1 tank also, so am I correct in thinking I need 1 bottle (can get this localy), 1 regulator, and 2 needle valves, I have syring bubble counters already are these sufient I hope if not oh well.
