RED SEA - Filter Media Cup - Filter cups

New filtration cups fitted as standard on the Reefer V3 in addition to the micronbag filters, the filtration cups are now available separately.

They are backwards compatible with previous versions of Reefer and the entire Max family. They are also compatible with many other brands because their diameter is 4". They allow you to use additional filter media (coal, resins, zeolites, etc.) without leaving them lying around in the settling and without using the micronbags as filtration bags.
