New tank, New filter, errrr

[warpedghost]

I purchased a 72g Bowfront tank that came with a Fluval 404 external filter.

I want to get the ProClear Aquatics Pro 75 Series Wet Dry Filter with Prefilter for it.

Question 1: Do I need the ProClear Pro 75 if I have the Fluval? I'm not really sure of the difference between the two.

Question 2: What is the difference?

Most of us use protein skimmers, not canister filters. You might just want to look up these products on amazon or another site that sells them to learn about them
