Brightwell's NitratR Regenerable Nitrate-Adsorption Resin is designed for all Marine and Freshwater Aquaria to improve water quality by removing excess nitrates. NitratR is highly selective for nitrates and will not negatively impact water quality, including alkilinity. These synthetic polymer resin beads allow for excellent flow through and maintained durability. The beads will not release nitrates back into the aquarium, even when exausted. Use in your Media Reactor or canister filter. May be regenerated over 250 times.
Prior to first use, rinse each 500ml of resin by passing 4 quarts of fresh water through it in a steady stream; discard water once completed.
Basic Instructions and Guidelines: To initially lower excessive nitrate, each 500ml of NitratR will remove 20ppm nitrate in 100 US-gallons of water (or 10ppm per 200 US-gallons). When nitrate concentration remains unchanged or begins to increase, regenerate as described below.
Advanced Instructions and Guidelines: To a point, effectiveness of resin is directly related to the reaction time it has with aquarium water; the longer the reaction time, the more effectively it will remove nitrate. Once the nitrate concentration (”[NO3 -]”) reaches a nearly-immeasurable level, NitratR will continue to remove nitrate as it is produced in natural biological reactions. Remove and regenerate resin when [NO3 -] begins to increase, then reapply to facilitate continued nitrate removal. In all cases, the use of a mechanical pre-filter to remove particulate organic material from water prior to its interaction with this media will prolong effectiveness. Fluidized-bed filtration: follow instructions of filter manufacturer for optimal volume of media to use in reaction chamber; start at a low flow rate and adjust to keep media in a steady “churn” within lower 2/3 of chamber; flow rate should not be such that resin is ejected into aquarium. Canister filtration: Load resin into filter cartridge as directed by filter manufacturer; leave resin in place until [NO3 -] reaches desired level or remains unchanged, as directed above. Slowing the flow of water through the filter may be required to obtain maximum effectiveness of resin. Passive filtration: Place resin loosely in a 300?m mesh filter bag and locate in an area of lowto medium-flow. Turning bag over periodically during usage will serve to shift the resin beads and increases effectiveness of this method.
To regenerate: Dissolve 4 cups table salt in 1 US-gallon of room-temperature water per 250-ml NitratR to be regenerated in a clean pail; place resin into pail and stir; allow beads to soak overnight; strain and rinse beads thoroughly in fresh water before re-using. Do not regenerate with bleach, which will damage resin and could kill aquarium inhabitants.
Caution: Keep out of reach of children. Not for human consumption.
Note: Resin sold moist. Keep closed to prevent drying. Weight varies due to moisture content, therefore product is sold by volume rather than weight.
