Filtration

[buster]

Hi, Everyone
I'm in the process of updating my aquarium set up. What is the
best filtration system? What is the difference between canister,
cascade, sponge. I do bi-weekly water changes of about 50%.

I like to have externals, more media less space in aquarium taken etc.

If all 4 pages get to be a bit much at least read page 4 about how the arrangement of media and the flow rate affect the quality of filtration.
