I'm setting up a new tank, right now I'm feeling proud of myself for managing to set up the tank -> canister -> heater -> tank circuit with no leaks (seriously, who decided that the only 300W external heater on the market would have a freaking 5/8" hose connector?). I'm planning to add carbon dioxide eventually, and I was thinking it would be a good idea to do so before I add fish, so any mishaps don't have major consequences. I've heard that you can run co2 into your canister filter (I'm using a Fluval FX5, which may be overkill for my 90 gallon tank) for diffusion purposes. Here are my questions:
(1) Does this work?
(2) How do you hook this up, physically? Do you run a line out from the co2 system and punch a hole into your filter input line? How do you do that without causing a leak and/or forcing water into your co2 lines?
