Anyone have ideas on how to disperse CO2 in my 10 gallon? I plan on growing demanding plants like HC and Glosso. Also I'm trying to keep the tank as sleek and low profile as possible. The reactor would be in the cabinet... but in the water a power head system would not be preferred (besides the current) because it would be hard to hide. I have a HOB filter so I can't run it through the canister... And I'm not sure if a ceramic stone would do the job well enough.... Any input or other ideas? Please and thanks!
