i guess this was the better place to post this question. ive been thinking about skipping the protein skimmer. does anyone out there run a reef tank without one? it just looks like the majority of what the skimmer actually takes out of the water is calcium and iron, 2 pretty important things for a reef. the biggest benefits that i know about it removing the film on the water to improve gas exchange and remove excess nutrients. but doesnt an overflow also remove that top layer?? and in a fully stocked reef tank would there be a huge excess of nutrients?
