I am still gettin loads of tiny bubbles in my tank due to the protein skimmer i think, how can i make ...
Its tough with those hang on style skimmer returns. If you are already trying a mesh covering over the outlet, then the tried and true method is not working, which makes this a challenge.
You could consider moving the skimmer to the far end of the tank and positioning the outlet over the far corner. Then build up a live rock structure so that the outlet is falling directly onto the rocks, allowing the rocks to break up the bubbles. This works well in sumps, so I would thing you could be creative and make this idea work in the tank.
Is the skimmer in a sump? If so slow down the amount of water returning fromt he sump to the display tank. If its a HOB skimmer, good luck! I personally don't like HOB skimmers for this reason. It makes it difficult to control micro bubblles.
