Evolution Aqua PURE Aquarium Nitrate Down is a specially formulated bacterial treatment, all-natural, for freshwater aquariums. Once added to your aquarium, each ball will reduce nitrate to a targeted level therefore there is less nitrate for algae to feed off. The protection continues through the month allowing multiple water changes without the need to add additional balls. The innovative biodegradable gel ball delivery method provides an easy way to dose your aquarium. Regular use of PURE Aquarium products will ensure that your fish live in a safe, healthy and crystal clear environment.
Use PURE Aquarium Nitrate Down whenever nitrate is detected or as part of your maintenance regime. For ongoing protection add 1 ball per 50L of tank volume per month, or as and when required to help reduce nitrate. In order to be effective a new dose should be added every four weeks. You cannot overdose with PURE Aquarium Nitrate Down and it can be used in conjunction with other PURE products in the family.
- PURE Aquarium Nitrate down is safe for use in all freshwater aquariums.
- We would always recommend the addition of oxygen into your tank using an air pump or venturi.
- Wash hands after use.
- Once opened, store with lid tightly closed in a cool dark place.
- Keep in a safe place out of the reach of children.
