In this post I will cover what I believe to be the most powerful form of filtration currently available to the saltwater aquarist. I agree that this aspect of filtration may not be for everyone, however by understanding what [tag-tec]natural filtration[/tag-tec] is and how it works then you can implement the type of filtration which is best for you.
There are various types of natural based filtration methods available – all of which never ceases to amaze me. The diversity of organisms which is in the aquarium is huge, to me these are just as interesting as the fish and corals which we keep. There have been numerous times when I have been sat in front of the aquarium when all the lights are out with a torch (with a red bulb in it) staring into the aquarium watching all the life go about its business.
