That Jabo is definitely a knock off Fluval 405 with some differences. I don't see the large side sponge filter to grab the large stuff. It also doesn't have the removable hose inlet/outlet on the top of the pump which would make cleanings a PITA as well as easy to snap off. It would work but it looks awfully flimsy. I'd rather have a Fluval 205 than a "Jabo 90G." However you're really limiting yourself with a filter that small.
The 501 should be criminal to sell with the amount of false advertising that thing has.
