CO2 injection practices
I read so many different ways to get the CO2 into the tank, reactors, diffusion glass, membranes etc. here is what I see
1. reactors may require an additional pump (powerhead etc), or inline with my canister.
2. Diffusion method does not require an additional pump in the tank, no additional electrical needs etc
Have i missed anything? What other things should I consider when deciding on a method and device. This will be a 72 gal system, and I will use a contoller.
