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.

Recommended Minimum MarinePure Amounts
Tank Size Spheres Plates Blocks* MP2C (for pond filters) MP2C-c (for pond filters)
50 gal. < 1 quart < 1 plate < 1 block n/a < 1 gallon
100 gal. 1 quart 1 plate < 1 block n/a < 1 gallon
250 gal. 2 quarts 2 plates 1 block ½ ft3 < 1 gallon
500 gal. 1-2 gallons 3-4 plates 1-2 blocks ½ - 1 ft3 1 gallon
2,500 gal. 3-4 gallons 12 plates 4 blocks 2 ft3 2 gallons
10,000 gal. n/a n/a n/a 8 ft3 n/a

* 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.

Recommended Minimum MarinePure Amounts
Tank Size Blocks in passive location
50 gal. 1 block
100 gal. 1 block
250 gal. 2 blocks
500 gal. 3 blocks
2,500 gal. 15 blocks
10,000 gal. 60 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).
