The PK100 Sponge Filter is suitable for aquariums up to 10 gallons. Measures 8.5cmx5cm.
Sponge filters are low-maintenance, easy-to-use, and gentle. Because they don't generate much current, these filters are ideal for:
-Aquariums that require gentle filtration/low current
-Breeding and grow-out tanks for fish and shrimp
It is recommended to use multiple sponge filters if your tank is overstocked with fish.
This filter requires the use of an air pump and airline tubing to operate (sold separately). Can also be used with a powerhead or canister filter.
