Aquarium Filtration; Canister Filters

[Carl]

I updated my Aquarium Filtration/Filter Review article with changes to the look and more importantly with much more information in the section dealing with Canister Filters.

I added a new picture and more information about the use of canister filters in hard plumbed/pre-drilled aquariums.
As well I added a section about micron canister filters.
