Fluval Lab Series Nitrate Remover

Rapidly remove nitrate and eliminate toxic nitrite in a matter of hours. Laboratory-grade, high-capacity ion exchange resin can be recharged simply by soaking in saltwater overnight - use over and over again. 150 g removes up to 25 mg/L (ppm) of nitrate in a 50 gal aquarium. Will not affect pH or hardness and contains no phosphates. Media bag included. For freshwater use only.

Caution
Due to the sensitive nature of many fish and invertebrates, it is strongly recommended to monitor the aquarium when using additives and filter media that affect water chemistry.

Special attention is required for planted aquariums.
The use of Nitrate Remover resin will affect nitrogen availability for plants. Use nitrate tests to monitor nitrate levels. Planted aquariums should maintain low levels of nitrate, approximately 5-10 mg/L.

Avoid using in conjunction with aquarium peat. Nitrate Remover will reduce the effectiveness of peat.

Directions for Use: For freshwater aquariums only.

1. Remove the nylon filter bag from the jar.
2. Rinse the nylon filter bag with its material under tap water before use to remove residue.
3. For best results, Nitrate Remover should be placed in the final stage of filtration to ensure it receives the purest water.

Maintenance
Use nitrate tests to measure the nitrate concentration. Once the nitrate's concentration reduction slows, or stops, immediately remove the resin. The amount of nitrate and/or nitrite removed will be proportional to the tank volume treated. Use the following chart to determine approximately when the resin should be recharged.

Each gram of resin removes up to 35 mg of Nitrate in freshwater.
Each gram of resin removes up to 30 mg of Nitrite in freshwater.

Note: Resin will not remove nitrite until all nitrate is removed.

Recharging the resin

1. Fill the container or another one of equal size with cold water.
2. Add 50 g of iodine-free aquarium salt.
3. Let the salt dissolve and add the entire nylon filter bag with used resin into the salt solution for 24-48 hours.
4. Shake the filter bag a few times while submersed for a consistent recharge.
5. When charge is complete, rinse in freshwater to remove excess salt.

This recharge process can be completed several times before material is exhausted. When not in use, Nitrate Remover can be stored in its original container.

Nitrate in your aquarium
In a natural environment, nitrate is removed through organic usage. In a closed system, however, nitrate gradually increases over time. This accumulation is due to the fact that it is the final byproduct of organic and inorganic degradation. Fish waste, decomposing excess fish food, dead plant and animal matter are contributing factors to nitrate accumulation. It is recommended to avoid overfeeding and/or overpopulating an aquarium to avoid excess nitrate.

High levels of nitrate promote the uncontrolled growth of algae. Additionally, several studies have shown high concentrations of nitrate considerably increase stress and reduce the capacity to resist several diseases in numerous species of freshwater fish. In order to maintain optimal water quality in freshwater aquariums, it is recommended to maintain nitrate levels of 20 mg/L or less.
