Anyone have a used CO2 bottle and/or a PH Controller?

Just recently picked up a calcium reactor and thought I would check here before going and getting them new.

Thanks!

You don't need to buy a CO2 cylinder. Go to your local gas place and they give them to you for a deposit. When it needs refilling you just bring it back and they swap it for a filled one. In Daytona it's AirGas, not sure what it would b by you. You might try the yellow pages under gas or welding supplies.
