Oase Pre-Filter Foam, Set of 4, BioMaster, 30ppi

This pre-filter foam set allows you to change the filter media of your Oase Bio Master quickly and easily.

Moving water is imperative for most aquarium fish, as this is the only way to ensure effective filtering and gas exchange. A certain amount of current in the water exists in their natural habitat and is important for their well-being. Furthermore, the aquarium water should always be filtered to ensure consistently good water quality.

The Oase Bio Master (not included) ensures effective filtering in your aquarium. The fine 45ppi pre-filter sponge ensures optimal mechanical filtration of coarse dirt and thus a longer service life of the biological media. The EasyClean pre-filter module also makes it unnecessary to remove the filter - you can easily remove, maintain and reinsert the pre-filter module.

Replace the filter media in your aquarium filter at regular intervals to ensure consistently high filter performance: in addition to changing the water, maintaining the filter is also important. However, you should either change the water or clean the filter (at the same time) so that not too many beneficial cleaning bacteria are lost. Wash the filter media twice under lukewarm water and replace them about every 6 months to maintain consistently good filter performance.
