Modern Reef's BIOReef-Snow is a product for natural clarification and biological removal of organic substances. It is used to bind fine suspended particles and organic waste, making them easier to remove through the skimmer or mechanical filtration.

It is a liquid suspension of natural microparticles that:

• bind organic waste and suspended particles,
• assist in their removal via the protein skimmer or filters,
• can act as a carrier for bacteria and coral food.
