It supports biological filtration by promoting anaerobic denitrification, effectively removing nitrates, nitrites, ammonia, and organic waste. Each liter treats up to 100 gallons, providing a compact, efficient solution without the need for special filters or cultures. ## Description Sachem Denitrate is a high porosity filtration product for the removal and control of nitrate in marine and freshwater aquaria by anaerobic denitrification. It is a porous inorganic solid about 4 mm in diameter. It does not require a special denitrifying filter or special culture feedings. It is also helpful in controlling nitrite and ammonia. The surface area characteristics of de*nitrate are similar to Matrix, making de*nitrate an effective support for the biological filter. Each liter treats up to 100 gallons. Marine or fresh water use. Review: Nitrate remover - Works great Review: MAGICAL - This is MAGICAL. I was measuring ~50ppm in my fully stocked 10g and 20g. After a few weeks with this stuff in my filter, my tanks just measured 2ppm in my 20g, and 10ppm in my 10g. It took a few weeks to work but I am so happy with it. I was looking at reverse osmosis and other options but they were far more expensive. My tap measures 40ppm, so this was a big problem. Other reviews mentioning that it quickly becomes ineffective and you must replace it regularly are misled. These rocks only allow denitrifying bacteria to grow on its very porous surface. As long as the filter isn’t clogged, these should work for at least a couple months. ## Features - For marine and freshwater - Provides support for biological Filter - Removes nitrates, nitrites, ammonia, and organics - The Package Weight Of The Product Is 1.78 Pounds ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000255PGC | | Allergen Information | Gluten Free | | Best Sellers Rank | #31,308 in Pet Supplies ( See Top 100 in Pet Supplies ) #299 in Aquarium Filter Accessories | | Brand | Seachem | | Brand Name | Seachem | | Customer Reviews | 4.5 out of 5 stars 1,239 Reviews | | Global Trade Identification Number | 00000116013703 | | Included Components | all | | Item Form | Liquid | | Item Type Name | Filtration Media | | Item Weight | 0.45 kg | | Liquid Volume | 1 liters | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 75181 | | Model Number | 19249 | | Number of Items | 1 | | Pet Type | Fish | | Target Species | Fish | | UPC | 707005129230 611102065134 000116013703 780231551136 015568976780 | | Unit Count | 1 Count | | Warranty Description | Warranty | ## Product Details - **Brand:** Seachem - **Item Form:** Liquid - **Item Weight:** 0.45 kg - **Liquid Volume:** 1 liters - **Unit Count:** 1 Count ## Images ![Seachem de*Nitrate 1 L / 61 cu.in. - Image 1](https://m.media-amazon.com/images/I/81hrV52PKQL.jpg) ## Questions & Answers **Q: Did anyone get 2l bottles with amazon being the seller? i tried twice and received 1l bottles. thanks!** A: 9/26/2017 Received my two containers today. Ordered two each of 2-liter size. Got two each of 1-liter size container. Shameful in my opinion! **Q: How do I use this product with a wet/dry filtration system?** A: Put it in a bag near the water intake tube, and make sure that the bag is fat (mine holds a whole jar) to keep the center protected from oxygen. You want a mild movement of water but not enough to disturb the inside bacteria. The outside bacteria will like oxygen, but to remove nitrates, you also need to colonize anaerobic bacteria. I have kept nitrates a zero for months now with no water changes, BUT I also dosed the tanks with BioDigest bacteria, which has both aerobic and anaerobic bacteria to eat nitrates. That combination seems to work well. **Q: what is the difference between this and matrix?** A: It’s the same it’s just smaller stones. No difference **Q: What filter can I use this in that is 50 gph or less rate?** A: You can use any canister filter with it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nitrate remover *by J***D on September 25, 2026* Works great ### ⭐⭐⭐⭐⭐ MAGICAL *by P***U on January 10, 2021* This is MAGICAL.
