Ocean Free Sponge Filter BF1

Innovative sponge filters for small or breeding tanks, where little water disturbance is needed. Provide exceptional room bacterial colonisation.
Multi-layered to give the best possible filtration and yet gentle enough not to create too much turbulence. Bio-Foam can be removed, rinsed and re-used.
Simply connect to an airpump, powerhead or hang on filter (not included).
The whole Bio-Foam area is efficiently used as a filter. No dead spots present.
Can be used on different filtration installations.
