This visibly porous inert biological media is especially suited for pond filtration.
The New and Improved - Supra + Biological Ceramic Ring Filter Media is the replacement biological media for all of the FishMate Bio and Pressurized Pond Filters.
Animate / FishMate had previously discontinued Item #231 - Supra Media and replaced it with this Item #349 - This media is New and Improved and offers superior biological activity.
Comes in a 500 gram box (about 1.2lbs) which covers about the same area of the 1.2lb bag of the previous media.
Supra biological media has over 100 times the biological surface area of conventional plastic media, and more than 5 times the surface area of traditional lava rock. The specific structure of SUPRA enables rapid growth of aerobic bacteria resulting in removal of lethal ammonia and nitrite.
