Hey all, I have a 4x2x2 planted with Co2. I wasn't happy with the water flow distributing the Co2 bubbles around the tank so I added a small powerhead , does the job very well. My question is.... I have the powerhead sitting about the diffuser to push the bubbles around. The powerhead itself sucks up quite a lot of bubbles and spits them out. Will this affect the Co2 ?
