that pondmaster pond filter is only the CANISTER portion. you still need to buy a submersible or inline pump (whcih has to be verypoweful0 to pump water into that canister.
that is designed for ponds - in theory it can be a giant canister but by the time you factor in the cost of that and a separate pump whcih you need and the power consumption of a pump, you are better off getting an fx5. FX5 is amazing, 1 will do your tank, your stocking is light - it will be more than sufficient.
a sump would be good too, maybe a small canister and a sump or a sump with a good turn over submersible pump.
you have to consider what pump you buy for your return pump.
cheap ones have very veyr high power use, so spending the money now for a efficient submersible pump will be more cost effective and you get return on investment generally after 8 to 12 months! (work it out, it stacks up)
sun sun pumps are 150 to 250watts.
eheim, via aqua, laguna is half that if not less! mroe efficient.
anyways, i would actually go for a canister if its not heavily stocked. you get better clarity of water with an fx5
