PURA NitrateLock is a selective ion exchange resin for nitrate removal in freshwater and saltwater aquariums. The media is regenerable 100's of times with the simple use of table salt. Capable of maintaining extremely low nitrate levels in your aquarium, use of NitrateLock can extend the time required between water changes.
Media comes conveniently packaged in its own 300 micron media bag for easy use. Follow directions for initial use, and regeneration process for best results.
500 ml (16.9 oz) treats 50 gallons for up to 24 months, monitor nitrate levels in your aquarium to evaluate media performance, and need for regeneration or replacement.
First Use Directions For Newly Purchased Resin:
Place media bag with resin in a gallon or larger container and soak in 0.5 gal of chlorine free water for 2 hrs. Drain and rinse with fresh water 5 times.
Place media bag with washed or regenerated resin into direct flow of water inside any filter or media reactor. High organic load and slime coat products reduce effectiveness of the resin and may permanently foul it. It is highly recommended to use high quality carbon for 24 hrs prior to introducing the resin.
Regeneration is accomplished by passing a flow of brine solution through the resin at a rate of 0.25–0.5 gal/min (1-2 qt/min), using a plastic 0.5 gal water pitcher with 1/8” hole drilled in the bottom. Visit www.magnavore.com for additional technical facts on resin regeneration and maintenance.
1. Prepare brine solution by dissolving 3.0 lb of table salt in 4 gal of chlorine free lukewarm water;
2. Place media bag with the resin inside the pitcher and fill pitcher with brine solution;
3. Lift media bag with the resin in and out of the pitcher several times to fluidize the resin, then leave it at the bottom of the pitcher. After brine solution drains out of the pitcher repeat steps 2 and 3 until all four gallons are used up;
4. Rinse resin as in step 2, this time using 2 gal of lukewarm chlorine free fresh water only. Drain, check the media bag for integrity and return resin to service.
