How do you CO2 your plants? All the dispensers I've seen would be way to small for my tank.. how would you CO2 a larger tank without it costing a fortune? Thanks

I'm not sure what you mean by "dispenser"... are you referring to the canister the liquid CO₂ is stored in, or the diffuser that causes the CO₂ to not enter the water as giant bubbles?

Yeah sorry got mixed up! . diffuser is what I meant. I dont really know how CO2 works so I'm a bit stuck with all the names etc.
thanks

Since you have a canister filter, you could choose to go with an inline diffuser, such as the one displayed in this video, or you could just choose a larger standard diffuser and use your filter output or a powerhead to move the CO₂ bubbles around the tank.

I use the CD5000 on my 90g, though I may switch to inline at some point in the future.
