Where does the protein skimmer pull the bad water from? Is it from fish waste, left over food, where ?? I'm asking this because I have 1 that was purchase from a LFS a home made skimmer for only $30. He was useing on his tanks and he was just replaceing some for his tanks so I said that I would purchase this nice looking one from him. It has been running now for a good 5 months now and it has only filled a 2 liter bottle 1/4 of the way. I do 20% water change every month and everything seems to be doing ok on my 75 gal reef. So I'm asking do you think that I should be looking for another skimmer?
