Internal filters

[cappa565]

Hey guys,
Got a 100L tank up and running, at the moment i have a internal filter which is around 10years old, im currently looking to buy a new one but am confused on what to buy, i would like the filter to have media or multiple stages of cleaning as my new filter only has sponges. It would be great if someone could point me in the direction!
Thanks

A hundred liters is ~50 US gallons, I think? If you want to stick with internal filters, the Fluval U4 might do the trick: Aquarium Filters: Fluval U-Series Underwater Filters from Hagen at fosterandsmithaquatics.com
