Does a protein skimmer use up more water?

Actually, you can still use filter pads... the cheap white fluffy stuff that is sold for this use is excellent. Change it every couple days and you're good... forget to change it and it becomes a problem. The skimmer is more like an advanced form of carbon, in that it removes dissolved organics (like how carbon removes the yellow coloration). It also removes proteins, aminos, lipids, and heavy metals.

I'm actually new to all this too, I've just been reading about it for over a year and finally have gotten my act together. Also, I retain a lot of what I read

I'm going to add a little bit here for you, jassz. Most people seem to have between 1 and 2 lbs of live rock per gallon of in the display tank. Less than this, and I suspect that there may not be enough surface area for the bacteria that keep reef aquariums going to colonize. Also, sand seems to be optional given enough live rock. It seems that the majority of people have around 30x circulation in their display, and around 10x through the sump (often less). These are my observations from reading a lot of posts. Most people use a skimmer... I wouldnt' run a FOWLR without one.

So yeah, go ahead and ditch that media! I followed up on another thread where the same thing was suggested, and the guy's corals have stopped dying, and are actually starting to come back.
