My tank has micro bubbles and film floating on the top and all i have is a rio nano skimmer and it doesn't stay primed and pumps out micro bubbles i need help how bad is this?
To get rid of the surface scum you need more water flow on the surface. Just a nice light ripple will be fine you don't have to blast it out of the tank. As far as the micro bubbles if the skimmer is still breaking in give it time. If that's not the case let's get a pic of the skimmer too.
