I just recently got a protein skimmer and this one sounded okay. The instructions that came with it were horrible so I may have set it up wrong (I looked at the picture and matched it).
I have also heard that they need to be broken in which could be the solution. I tried putting it into a different tank that has nothing in it other than the water from my tank but bubbles still remain in my current tank. Any sort of movement such as a rock moving brings out a bunch of bubbles everywhere. Is there any way I can get rid of them? Not to mention one of my fish just died after noticing there were bubbles all over it. Any help will be appreciated, thanks
