I've got mainly softies I could frag up. Finger leather and toadstool. I could buy it off you if you weren't interested in those.

Can one co2 canister be split between two tanks? I wanted to use it both for a calcium reactor on my 120g reef and for co2 injection on my 20g planted tank I just started up. The planted tank would be using a controller, so it'd be turning on and off. Would that affect the calcium reactor? I'm thinking running the two tanks off the one would save $$ because the 20g planted tank would require very little co2 compared to the calcium reactor I think.

How would I hook two needle valves and bubble counters to the one tank?
