Description

Seachem De*nitrate 100mL — High-porosity natural mineral filter media for biological denitrification of aquariums

Seachem De*nitrate 100mL (SKU: 724953-135) is a high-porosity natural mineral filter media designed to remove nitrate, nitrite, ammonia, and organic contaminants through biological denitrification. Its pore structure supports anaerobic denitrifying bacteria at low flow rates (<200 L/h or 50 GPH).

Seachem de*nitrate is a porous filtration media that efficiently removes nitrates, nitrites, and ammonia by supporting beneficial bacterial growth within its structure. It works best in low-flow environments and treats up to 200 litres per 500 mL, helping maintain healthy water quality in both freshwater and saltwater aquariums.

Usage & Application

When to Use

  • Nitrate Control in Small Tanks: Ideal for controlling nitrate accumulation in nano aquariums, small canister filters, or internal filter chambers.

  • Biological Filtration Upgrade: Enhances standard biological media by target-removing nitrate without chemical resins.

Placement & Flow Guide

  • Place in a media bag within a filter chamber with controlled low water flow (under 200 L/hr or 50 GPH).

  • Rinse under tap water prior to first installation to remove mineral transport dust.

  • If flow exceeds 200 L/hr, use Seachem Matrix instead for general bio-filtration.
