What we liked
- + Listing describes double filtration: a circular bio cotton sponge plus a chamber with bio-ceramic balls.
- + Two sponges are included so one can stay on the filter while the spare is swapped in, per the listing.
- + Runs from an air pump with no motor in the tank, a common choice for fry, shrimp and betta tanks.
Trade-offs
- - An air pump is required and is not part of this listing, so it adds to the cost.
- - This is the larger size than the 8 to 20 gallon model it replaces, so check that it fits a smaller tank.
