Lee's Large Bio Pin Balls are state-of-the-art filter media designed for superior biological filtration in saltwater wet/dry aquarium systems. This innovative media effectively supports the crucial process of breaking down toxic ammonia into less harmful nitrates, ensuring a healthier aquatic environment. They also play a vital role in producing turbulence within the filter, significantly aiding the gas-exchange process.

Each Bio Pin Ball is engineered with 150 Bio-Pins, providing extensive surface area for beneficial nitrifying bacteria to colonize. The unique design allows them to be connected together for structured placement or randomly placed within your filter box. With 74 balls per gallon, the void space between the Bio-Pins is optimized for the movement of essential gasses like oxygen, ensuring it readily contacts the bacteria. For saltwater applications, the suggested usage is one gallon of Bio Pin Balls per 20 gallons of aquarium water.

This filter media is ideal for saltwater reef hobbyists utilizing wet/dry filtration who are dedicated to maintaining pristine water quality and robust biological stability in their tanks. By providing an exceptional habitat for beneficial bacteria and enhancing crucial gas exchange, Lee's Large Bio Pin Balls help create a thriving and balanced ecosystem for your marine inhabitants.
