Oase Set Blue Sponges 45 ppi Prefilter Biomaster

With this set you can change the filter material of your BioMaster Oase quickly and easily. With Oase BioMaster (not included in the supply) ensures effective filtration in your aquarium. Thanks to the EasyClean prefilter module, you do not need to remove the filter: you can easily remove and re-enter the prefilter module.

From time to time you should replace the filter material in the aquarium filter to ensure consistently high filter performance: besides changing the water, the care of the filter is also important. However, you should change the water or clean the filter, so as not to lose too many bacteria useful for cleaning. It is possible to wash the filter media about twice under warm water and replace them about every 6 months to maintain consistently good filter performance.
