Maxspect’s Nano-Tech Bio-Plug represents a revolutionary advancement in frag plug technology, offering a dense arrangement of small spheres that create an exceptionally porous surface area, ideal for stimulating coral growth. The innovative design of the Bio-Plug enables water current to penetrate the plug from both the top and bottom, facilitating easier nutrient extraction by coral frags. This unique porous structure not only benefits coral growth but also serves as a highly effective bio-media. The cross-cutting surface area of the ceramic material provides an ideal habitat for beneficial bacteria, aiding in the removal of ammonia and nitrites from the aquarium water. As the bacteria thrive on the bio-media, they become readily available as food for coral frag polyps, further enhancing the growth rate of coral frags. Each pack contains 25 Bio-Plugs, offering aquarists a versatile and efficient solution for coral propagation and aquarium biofiltration.
