I don't like systems with built in filtration. Eventually, that filter fails. An Aquaclear HOB runs for 15 to 20 years if well maintained. When you're 20, that sounds like forever, but a tank is generally good for 30. And the Aquaclear is the longevity champion. If the filter fails at 5, then built in is bad.
I'm assuming from others the Juwel is built in.
US brands like Marineland have died at under ten, way under ten, and my no name Chinese ones are making 12-15 before failure. I run canisters in some applications, HOBS in others, sponges and corner box filters, some homemade in many, and old fashioned undergravels in some. I have a fishroom with many tanks.
I'm a cheapskate who tends to improvise a lot.
Which filters I use depends on the needs of the fish. A powerful canister isn't good for fish evolved for slow water, but a fish from the edges of a rapids isn't going to thrive with a box filter. An undergravel isn't good for corys, and so on. The word 'fish' is useless for an aquarist, and you have to think species by species. The word 'filter' can be just as useless as they aren't all designed to work the same way or do the same thing.
