I would suggest an external canister for a tank that large it's better to over filter than under so never fear going with to much filtration I have a canister on my 35 gal community tank which has an hourly rate over a 1000gal/hr the larger out lay of cash now will save you so much money in the future and so much time
Hope this helps
I checked out some of those filters and they are pretty neat! I'm probably going to get one of those when I start my next tank! But first, I need to get this one going!
