Promotes growth of beneficial bacteria Helps reduce ammonia and nitrite over time Easy to clean and long-lasting Beneficial bacteria are the key to a healthy aquarium system as they effectively remove toxic ammonia and nitrite from the water column. Improve the good bacteria count in your aquarium by adding bio rings to your filter. They are great for use in canister filters, hang on back filters, sumps and more. The shape and porous design of these rings is intended to maximize the amount of surface area for beneficial bacteria to live and for water to flow freely through the rings. 1 bag of bio rings weighs 1lb 2 oz (500 grams) For optimum efficiency, it is recommended to clean your bio rings every 1-3 months as needed. To clean, simply rinse in dechlorinated or tank water until debris has been loosened and removed.
