CO2 solution works, but not with air pump!
So this is my first DIY (or otherwise) experience with CO2 for planted tanks. I know my solution is working because my tubing will spit out bubbles, however once I try to hook it to my diffuser...a power head, my CO2 goes back several inches and just sits in the tubing. Do I need a different power head or is there an issue with my pressure or..?
