Sale price$13.98
Size: 200ml


  • Ideal for Freshwater, Saltwater & Reef Aquariums
  • Natural removal of nitrate and phosphates
  • Reduces aquarium maintenance and optimizes water quality

Recommended Dosage: Add (4ml) for every gallon of aquarium water or 40ml for 10 gallons. One container treats up to 50 gallons.

How to: We recommend using NPX Bio-Activated Polymer in a media reactor or in a filter container that will keep the NPX Polymer in constant motion with consistent water flow. Media that becomes stuck together should be separated or removed. The use of a good protein skimmer is strongly recommended when used in a reef aquarium.

How often: Keep NPX Bio-Activated Polymer quantity consistent by replacing product consumed by bacteria.  Product normally lasts between 3 and 6 months.

Please Note: It normally takes between 2-4 weeks for the product to become active and start naturally removing the phosphate & nitrate. To prevent the possibility of cloudy water caused by a bacteria bloom, we recommend starting out with a half dose and slowly adding product weekly until proper dosage is achieved.
