Aqua Clean Bio Block (Marine Special) is a premium biological filtration media engineered specifically for marine and reef aquariums. Manufactured using high-grade inert ceramic (Al₂O₃), this bio block delivers exceptional biological performance while maintaining ultra-low phosphate and aluminum output, making it completely reef-safe.

Its open porosity structure allows high water flow without clogging, creating ideal conditions for beneficial bacteria to thrive and efficiently remove ammonia and nitrite, while helping to minimize nitrate buildup.
