GEX Slim Filter Reinforced Filter Media Cavity 30 pcs

Reinforced filter media compatible with all sizes of GEX Slim Filters.

We have prepared a pack of 30 pieces.

15 cavities fit into the space on the right side of the Slim Filter.
Simply place them there, and it will lead to water quality stabilization.
It fits into the red frame in the second image.

After about a month of actual use, the water quality has stabilized, so we are now starting sales.
I personally like it because there is no decrease in water volume.
Genuine filter media is expensive, so I hope to extend the replacement frequency even a little.

Please ask any questions you may have.
