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.

Usage Recommendations 

 

Nitrification

Recommended MarinePure amount for to eliminate ammonia and nitrite in an active filter, for a typical bio-load.

Tank Size	Spheres	Plates	Blocks***
50 gal.	< 1 quart	< 1 plate	< 1 block
100 gal.	1 quart	1 plate	< 1 block
250 gal.	2 quarts	2 plates	1 block
500 gal.	1-2 gallons	3-4 plates	1-2 blocks
2,500 gal.	3-4 gallons	12 plates	4 blocks

*** MarinePure's thick blocks are designed to be used in passive systems to control nitrates. If used in active systems they will eliminate ammonia and nitrites (nitrification).

 

Denitrification

Recommended MarinePure amount to minimize nitrates in a passive filter, for a typical bio-load.

Tank Size	Block in Passive Location
50 gal.	1 block
100 gal.	1 block
250 gal.	2 block
500 gal.	3 blocks
2,500 gal.	15 blocks

* MarinePure's thick blocks are designed to be used in passive systems to control Nitrates (like live rock). If used in active systems they will eliminate ammonia and nitrites (nitrification).
