After a few years of owning and maintaining a fish-only freshwater aquarium, I am gearing up to start a planted aquarium. I wanted to upgrade in size, so I am taking this opportunity to start with new substrate (since I only had cheap gravel to start with) and start growing plants. I am wondering who all of you use for your CO2? I would normally ask they people at the Reef, but unfortunately, they've closed up shop - kinda sad, actually...
Incidentally, I'll have a 55G tank, stand, and top up for grabs for anyone willing to provide muscle to assist with the transition. ...whenever the new tank and stand arrives.
