OK, I can't figure out how to attach a picture, but if you go to the Drs Foster & Smith website and look at the Simi-Automatic CO2 System, maybe you can answer my question. And when I say "you", I mean anyone.
With this system, I would just have to get a canister, and hook it all up? And that's it? What size canister would I need for my 75g?
Please, any help on this would be greatly appreciated.
