I cranked up my pressurized CO2 about a week ago with a 2 1/2 lb tank. Today it is empty so I learned a $10 lesson. I was anxious to start and didn't check the system for leaks and today ARGG it quit. Just a reminder to check for leaks with soapy water and save a few bucks. Now I have to wait til I can fill it again to restsrt so no CO2 and the plants were doing just great.
