MarinePure ROCK
Ammonia, Nitrite, and Nitrate Removal
The perfect substitute for Live Rock- safe, effective, and economical.
Primarily designed to provide deep anaerobic zones for de-nitrification. Great for aquascaping and as a substrate to grow corals.
Use directly in Aquarium tank - available in small or medium sizes
MarinePure is the perfect place for beneficial bacteria to flourish in order to remove harmful fish wastes. It will eliminate ammonia and nitrites and lower nitrates.
MarinePure's bio-media is the most technically advanced bio-media available today.
Features Thin Bio-Film Technology
MarinePure is inert and will not harm aquarium inhabitants.
Why Use MarinePure?
Better value due to high performance
Reduced tank maintenance
Allows for higher fish loads
Can use a smaller filtration footprint
More consistent water chemistry
Easy to shape
Can be used in a variety of applications;
Used in tank
Used in sumps
Used in canister filters
Used in DIY filters
Used in trickle or shower filters
Used in waterfall filters
Used in hang on back filters
Thin Bio-Film Technology
Combination of vast surface area and open/interconnected pores allow a thin bio-film to develop.
This thin film allows bacteria to flourish because necessary nutrients are immediately available.
With the open pores, old dead bio-film is easily flushed from the media and will not plug the media.
Water flows through the media, not around as with other denser medias, thus utilizing the most surface area for beneficial bacterial growth.
MarinePure Technical Info
MarinePure is designed to be a substrate for bio-filtration, specifically to target ammonia and nitrite removal (nitrification) and to minimize nitrates (denitrification). MarinePure is suitable for both freshwater and saltwater (marine) environments. MarinePure can be used fully submerged or in trickle/shower filters. It should not be used in moving bed filters.

MarinePure Instructions
MarinePure is designed to be a substrate for bio-filtration, specifically to target ammonia and nitrite removal and to minimize nitrates. MarinePure is suitable for both freshwater and saltwater environments. MarinePure can be used fully submerged or in trickle/shower filters.
For removal of Ammonia and Nitrites (Nitrification)
Initial rinse of media with water to remove surface particulate created during shipping.
If tap water is used, perform second rinse with tank water to remove chlorine.
Locate media in filter, sump, under gravel bed, anywhere in the tank or as part of a reef structure. Locating within the flow of the water will give the most efficient results.
NOTE: the product is easily shaped using a hand saw or coarse sand paper. Make sure to rinse particulate before placing in tank.
Wear a a dust mask to avoid breathing in particulate
Mechanical filtration of water, such as with matting, is recommended prior to water entering MarinePure product
For removal of Nitrates (Denitrification)
Initial rinse of media with water to remove surface particulate created during shipping.
If tap water is used, perform second rinse with tank water to remove chlorine.
Locate media in a passive location such as in a sump, under gravel bed, or as part of a reef structure.
NOTE: If desired, the product can be easily shaped using a hand saw or coarse sand paper. Make sure to rinse off particulate before placing in tank.
Wear a a dust mask to avoid breathing in particulate
Maintenance for flow-through filter systems
Periodic backwashing or rinsing using tank water suggested every 3 months or as frequently as necessary.
Maintenance for passive filter systems
If necessary, backwash and / or rinse as described above.
Although product should be self-cleaning, applications and use vary.
A weak acid can be used for cleaning, but time in acid conditions should be minimized. Make sure to wear appropriate Personal Protective Equipment when using acid.
