Hey guys! I bought an aquarium kit that I’m turning into a nice little shrimp tank, and while I know a sponge filter would be the best option, I decided to try out the tetra whisper internal power filter that came with the tank. have never had an internal filter before (only HOB) so I’m a bit confused with how this works. How is the filter cardrige even filtering anything since the water comes from the bottom? Anyways, the water is coming up over the cartridge and flowing down, but it can’t be clogged because I just set it up. It is supposed to do that? I’ve tried looking it up but haven’t really got any answers. Thank you!!
