As stated above I have a reef octopus 220-S classic internal skimmer. I really like it. Problem is twice over the last month the thing for no apparent reason starts to overflow. It runs great and then boom full skimmer cup sump full of skim mate big mess gross! I don't get it. I do have my airline going to the garage and it probably did start when I put the line out there. Would temperature effect the surface tension in the skimmer? Thanks for the ideas and suggestions!
