GARF'S NEW INTERN - ARTICLE BY TREVER - BULLET PROOF REEFS

Perhaps the most important element
of the Bullet Proof reef system is live sand or GARF Grunge.
This product seeds the Aragocrete with Coralline algae, and it supplies millions of good bacteria

Grunge (sold through GARF) is cultured sediment; thousands of different species of bacteria and billions of individual bacterium live on every teaspoon of GARF Grunge. Marine fungi, coralline algae and other organisms are also present in Grunge. The Grunge is placed on top of the substrate once water has been placed in the tank, and will immediately start to work on the aquarium. Grunge primarily assists in the denitrification process, ridding the aquarium of animal waste products. However, because of the great species diversity in Grunge (much like on the ocean floor), the organisms will improve the tank in other ways. As a rule, the more species diversity in an environment, the more stable the environment will be. Grunge adds diversity to a tank, and if for example there is a mushroom coral in the tank which produces a certain colloid which may hurt Montipora corals, there is bound to be some organism in the Grunge which will use that colloid, rendering it harmless.
