Keep your aquarium water cleaner and healthier with Fluval Nitrite Remover Pads, specially designed for Fluval 307 and 407 external filters. These replacement filter pads combine chemical and mechanical filtration to reduce harmful nitrite levels while capturing fine debris, helping maintain clear water and a healthier environment for freshwater fish.

Key Features

• Reduces Harmful Nitrite – Effectively removes nitrite from aquarium water, helping maintain safer conditions for fish and supporting a balanced aquatic environment.
• Chemical and Mechanical Filtration – Dual-action filter media reduces nitrite while trapping suspended waste and fine particles for improved water clarity.
• Supports Fish Health – Lower nitrite levels help reduce stress on fish, making these pads particularly useful during new aquarium setups, routine maintenance and after increasing fish stock.
• Ideal for New and Heavily Stocked Aquariums – Provides effective nitrite control where water quality can change quickly, helping maintain stable conditions.
• Made for Fluval 307 & 407 Filters – Precision-cut replacement pads fit directly into compatible Fluval external filters for quick and simple maintenance.
• Convenient 6-Pack – Includes six replacement pads, providing a practical supply for regular filter maintenance and consistent filtration performance.

Nitrite can become harmful when biological filtration is still developing or when aquarium stocking levels increase. Fluval Nitrite Remover Pads help manage these conditions by continuously reducing nitrite while removing fine debris from the water. Regular replacement helps maintain effective filtration, cleaner water and healthier conditions for freshwater aquariums.
