Replenish your testing supplies with the Red Sea Nitrate Pro Test Kit Reagent Refill. This refill pack provides all the necessary reagents to continue using your Nitrate Pro test kit, an advanced colorimetric comparator test designed for precise measurement of nitrate levels in your saltwater reef aquarium. Accurate nitrate testing is a critical component of the Red Sea Reef Care Program, enabling precise dosing of nutrient reducers like Red Sea’s NO3:PO4– X for optimal water quality.

This high-quality reagent refill allows for 100 nitrate tests, offering exceptional value and longevity. The test maintains the system's exceptionally high accuracy of 0.125 ppm, allowing for the detection of even subtle changes in water chemistry. It measures a wide nitrate range from 0 to 64 ppm, making it suitable for various stages of a reef tank's life, from ultra-low nutrient systems to tanks with higher nitrate levels.

This reagent refill is specifically for reef aquarists who already own the Red Sea Nitrate Pro Test Kit and need to restock their supplies. It is ideal for hobbyists who are serious about nutrient control and maintaining a stable environment for sensitive corals. If you are actively dosing supplements to manage nitrates and phosphates, the consistent, high-precision results provided by these reagents are indispensable for preventing nuisance algae and promoting vibrant coral health and growth.
