Lee's Small Bio Pin Balls offer a cutting-edge solution for enhancing biological filtration in both saltwater and freshwater wet/dry systems. These balls are designed to increase water turbulence within the filter box, thereby boosting gas exchange efficiency, which is crucial for sustaining healthy nitrifying bacteria populations. Each ball contains 110 Bio-Pins that create a vast surface area of over 130 square feet per cubic foot of media, making it highly effective in breaking down harmful ammonia and converting it into less toxic nitrate.
