IME Purigen does do best in a canister because it lets very little water flow around the media and will force it through it making it more effective.
I have had friends use it in sumps/HOB
filters and will either use 2-3 bags of Purigen or use filter floss to help force the water through the media and it's worked for them but tends to be more of a pain.
If you do get a canister then anything in the 200+ GPH
range should work fine.
I use the Magnum 350 Pro
on my 55 with both wheels spinning and love it personally but the Magnum 250
, FilStar Canister Filters, Eheim, & Fluval canister filters are all excellent as well.
A lot of people will tell you to ditch the bio-wheels due to them being no3
factories but IME it hasn't been the case and I enjoy being able to transfer one to my QT at anytime for "instant" bio-filtration if needed
Only thing to really remember about HOB
filters/canister is to keep them cleaned weekly rinsing off anything that traps waste.
