Kurt, you really should read all the info on this site.

Which FAQ? I haven't seen one float by. I bought "The Reef Aquarium:
Science, Art, and Technology, Vol. 3", and I'm still waiting for delivery.

I have a very thin substrate, so it's not much of a filter system.
Besides, there's plenty of material that I couldn't reach around and
behind the rocks. I'll keep it mind ...
