USB FILTER
This tiny USB filter looks like it shouldn’t work, but it does the job I actually want: a bit of water movement and polishing. I don’t rely on it for biological filtration in a heavily planted tank—most of that happens in the substrate and plants. I like to add a bit of filter floss to make it polish properly.
Pros
- +Small and simple for gentle flow
- +Useful for surface movement and water polishing
- +Works well alongside a strong planted/substrate system
Cons
- -Not enough filtration on its own for most setups
- -Stock sponge media is too coarse for fine polishing
