What does a protein skimmer actually do?? What does it connect to because i have a Ecplise 2 30 gal tank. I don't any place a skimmer could go because it is a closed top. Do it connect to a filter or what??????
A skimmer flows water through minute air bubbles...the air bubbles attract organics which stick to them and take a ride upward into a collection cup where the bubble erupts leaving the organics in the cup...pretty effective.
Generally, skimmers come it two varieties...hang-on (the side of the tank), or in sump...submerged in a sump.
I do not know of any skimmer which can be used on an enclosed Eclipse system...maybe someone else here does..
