please explain my protein skimmer
I have a 55 gallon saltwater tank with seven small fish and coral. My filter is marineland and can filter a 110 gallon tank. The other day I added coral and rearranged the live rock etc. My protein skimmer started acting strange in that the little tornado in it looked more like a really dirty sand storm and the output poured a fog of tiny bubbles.
I took it out, took it apart and cleaned it and put it back. Now I can get the tornado back but it is not bubbling into the upper chamber (discharge cup) at all. If I turn the air intake up, I get the sand storm effect again. At this point, I have a small tornado and my output is releasing clear water with intersperced larger bubbles. It is doing what it did initially on installation for about 2 months. then one day, somehow it started to bubble up to the upper cup and I was happy that it was working.
I read that unless I want to do lots of water changes, I need a protein filter. I am happy to keep it but do not understand it at all. Do you think it is working from my description?
Thanks in advance!
