Reef ACTIF is a adsorber and bacterial nutrient for saltwater aquariums. The product is suspended in the aquarium water where it bonds with both nutrients and water contaminants making them available as nutrients to bacteria and other animals that feed on dissolved organic material in the saltwater. This product which is now available in the states should be arriving in your local retailer soon if it hasn’t made it there already. We aren’t sure about a retail price but we got word in to Tropic Marin so rest assured we’ll keep you updated.
