Unlike rocks commonly found in the market, AF Rock primarily excels in efficient filtration. Thanks to its high porosity, it facilitates the colonization of bacteria and serves as an excellent filtration medium. Unlike live rock, the use of AF Rock guarantees that you won’t introduce harmful and invasive organisms into the aquarium, such as valonia, aiptasia, dinoflagellates, or bryopsis. The handmade nature of AF Rock ensures the uniqueness of each set and provides a distinctive shape for all elements. High porosity ensures low weight and an excellent mass-to-volume ratio. As a result, AF Rock is significantly lighter than other rocks available on the market.
