Brightwell Aquatics Purit is a next-generation combination of enhanced activated carbon and NSF-grade ion-exchange and adsorptive resins. The carbon in Purit offers superior chemical filtration performance over traditional activated carbon and combined with the ion-exchange resins will enhance the removal of impurities such as ammonia, nitrate, phosphate, silicate, heavy metals and dissolved organic material from the aquarium water.



  • Facilitates decomposition and oxidation/reduction reactions, enhancing oxidation-reduction potential (ORP), and improving water quality.
  • Improves water clarity by removing dyes and organic discoloration.
  • Eliminates odors caused by decaying organic material.
  • Removes copper from medicated systems.
  • Removes lead and other heavy metals.
  • Completely Reef Safe



Instructions and Guidelines

Prior to first use, rinse Purit under a stream of fresh water, then discard water.


*Used as directed, each 100 ml of Purit will help maintain water quality in 25 US-gallons (94.6 L) for up to 6-months, depending upon system's bioload, rate of nutrient input to system, initial nutrient concentrations, and efficiency of pre-existing filtration. Expect Purit to exhaust more rapidly during the first application if the system is high in dissolved organic material. Subsequent applications will yield positive results for a much longer period of time. Proper and sensible management of aquarium chemistry by limiting the rate of nutrient input (e.g. not overfeeding or overstocking an aquarium system) and performing regular water changes will prolong the effectiveness of Purit.


Media Reactor Use: Load Purit into filter cartridge, or into in-line media housing, as directed by filter manufacturer. Some canisters may require that the media be housed inside a mesh bag, within the housing. Use a 150-micron mesh filter bag (included) in this case.


Passive filtration: Place Purit loosely in a 150-micron mesh filter bag and locate in an area of low-to-medium flow. Turning bag over once weekly will serve to shift the media and increases effectiveness of this method.


The use of a mechanical pre-filter to remove particulate organic material from aquarium water prior to its interaction with Purit will prolong the media's effectiveness. Regardless of the method of application, slowing the flow of water through the media will improve its efficiency. In general, forced, laminar flow (e.g. flow in one direction, not turbulent or \"fluidized\") of aquarium water through Purit will result in more rapid extraction of impurities than will placing the media inside a mesh bag and allowing it to passively remove impurities. Therefore, placing Purit in a media reactor or canister filter for the first one or two applications to an aquarium will result in a significant decrease in the concentrations of latent dissolved organic material and other impurities, helping bring them under control. Subsequently, Purit can be employed in a mesh bag, if desired, for long-term control of nutrients and impurities. Discard and replace Purit when signs of water discoloration begin to re-appear in aquarium system. If using to remove chloramines from tap water, perform a test on filtered water to verify that Purit has not become exhausted prior to adding the water to an aquarium containing living organisms.


Caution: Keep out of reach of children. Not for human consumption.
