I ran the exact same canister filter with a sump. I can tell you those are less eficient and much more maintenance v. a sump and everything a sump provides. I tossed mine when I updated to a new sump. My advice would be to return the canister filter and get a sump that will allow you to grow. I purchased the new 3rd generation Eshopps RS-300. Easy setup, low maintenance, very quiet and works great. I have a vertex omega 150 skimmer in there along with a pump for the GFO reactor, a pump for Carbon reactor, a pump for the emporer aquatics 40 Watt UV, and a sponge filter and two heaters. There will be some great deals coming up in the next week or so. Your stand provides you with plenty of room for a good sized sump. Why not take advantage of that? I think the route your going with the canister filter, you're taking three steps back.
