MARIN FILT
Highly porous, cacium-free filter material for seawater aquariums. Marin Filt is made from pure baked porcelain clay. Its numerous fissures make it perfect for growing aerobic bacteria. Marin Filt can be used easily and conveniently in any filter system (multichamber filters, suction filters, trickling filters, surface and floor filters). Due to its composition, Marin Filt remains loose, preventing the formation of karsts in the filter material. The product is highly durable. In contrast to calcium- based filter materials, Marin Filt does not eliminate any other minerals, and the filter is not clogged after a short time. With Marin Filt in The filter, your seawater aquarium is quickly ready for full use.

MARIN GRAN
is baked from the same material as Marin Filt. This highly porous, loose and light floor material prevents the forming of putrid mud and provides
natural housing for floor-dwellers. Tube worms, cylinder roses and other invertebrates love to dig themselves into this loose floor material. Wrass and gobies can chew up the floor material and hide in it without danger. You may mix Marin Gran with Alpha Marin and/or chipped coral. Marin Gran safely prevents the formation of karsts in the floor material. .
