The high level of biological activity prevalent in intact coral reefs means that high concentrations of biopolymer substances can be found there. Contact with nutrient particles and colonisation with specific bacteria lead to the formation of particles that have a heightened level of nutritional value and are even visible to the naked eye. These flaky and filamentous particles are referred to as reef snow.

Tropic Marin® Reef Snow contains these natural marine biopolymers. Together with other feedstuffs, they form nutrient-rich flakes that resemble natural reef snow which are then passed on to the corals and other filter feeders. The concentration of a Tropic Marin® Reef Snow solution can be varied in order to adapt the size of the flakes to suit the filter feeders contained in the tank.
