Mantis Bio-Filter Blocks offer a highly efficient solution for aquatic bio-filtration. Constructed from inert ceramic material, these blocks boast an open flow architecture and provide the largest usable surface area for optimal biological filtration. Their microporous surface supports the growth of diverse microorganisms, forming a stable and active biofilm to treat NH4-N and NO3-N effectively. These blocks are suitable for a wide range of filtration systems, including sumps, trickle filters, wet/dry filters, and can even be placed directly in the tank. Versatile in functionality, they are adaptable for use in fresh, marine, and pond water environments. Key Features: Microporous surface enhances biofilm development and microbial growth. 3D void structure promotes effective water flow and microbial activity. Compatible with various filtration systems, including sumps and trickle filters. Suitable for fresh, marine, and pond water applications. Provides an excellent base for sponge growth, micro-fauna, and coral frags. The Mantis Bio-Filter Blocks are engineered to maximise biological filtration efficiency, offering a technically advanced substrate for aquarists seeking reliable water quality solutions. With their unique structure and versatile application, these blocks are ideal for maintaining healthy and thriving aquatic environments. Specifications: Block dimensions (LxWxD): 10 x 10 x 2.5 cm Material: Inert ceramic
