AC Marine-Spec Bio Block: Specifically designed for marine aquariums and coral reef tanks

In marine aquarium maintenance, phosphate accumulation and water quality fluctuations are major threats to the health of corals and fish. Designed specifically to address this, the AC Marine-Spec Bio Block features an extremely low phosphate content (only 0.0274%) and controlled heavy metal release, providing a stable and clean environment for saltwater aquariums.

Its open-pore structure enhances water flow, prevents clogging, and offers ample surface area for nitrifying bacteria to colonize, continuously breaking down ammonia and nitrites to maintain long-term water quality balance. Suitable for both fish-only and reef aquariums, it helps create a clear and healthy marine micro-ecosystem with peace of mind.
