Description
8″x8″x4″ Block
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™ Blocks are designed to allow the growth of both aerobic bacteria (near the surface) and anaerobic bacteria (internal). The growth of these bacterias allow for removal of ammonia, nitrite and nitrate. For optimum anaerobic growth, place in slower flow. Excellent for skimmer riser, but can be placed anywhere in the water column. MarinePure recommends one block per 100 gallons of saltwater system.
8″x8″x4″ Blocks are great for larger aquariums. Just drop them in your sump or wet/dry filter.

* 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).
DenitrificationRecommended 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).
