co2 leaking

  1. Equipment
    Just hooked up my SR Aquaristik regulator to a brand new CO2 cylinder and I'm getting a small leak coming from where the regulator threads on to the cylinder valve. I've tried wrenching the nut down as tight as I can but it's still leaking slightly. I've thought about pipe dope or Teflon tape...

    Over the few days I've been noticing my drop checker getting bluer, so I upped the bubbles per second.. I think I had it up to 5 bps. Today while I was re-arranging the cabinets I check on the co2 regulator again and the tank reads as empty! I filled it up with co2 about a week and a half ago...
