Hello All! I have a 20 gallon Ultimate Nature tank that I planted 8 weeks ago. I filled it with water 2 weeks ago and purchased a Fluval CO2 cartridge system and set it up. When I turn it on I get like one bubble every minute or so. I have the valved turned all the way on -- any ideas on how to get the regulator working properly? Thanks so much! Diane

It's probably out of CO2, have you been running it for 2 weeks now? Those small disposable cartridges don't last very long.

I agree with Quagulator; the small cartridges last around the time you have described.

I usually recommend, at the smallest, a 5 pound cylinder
