Increasing flow in Fluval Edge 12
I'm really struggling to get CO2 dispersed in my Fluval Edge 12 gallon tank. It is very heavily planted, and the flow from the filter just doesn't seem to be doing the job anymore. I'd like to add a pump or power head of some kind to get some flow around the bottom of the tank, but I've never used one, and I'm not sure what I should be looking at for such a small tank. Any suggestions?
