Tropic Marin Reef Actif

Tropic Marin Reef Actif is a natural reef aquarium supplement that keeps water clear and stable between water changes while bringing out richer color in corals and clams. It works two ways at once, binding excess nutrients and pollutants like an adsorber while feeding the beneficial bacteria that break those compounds back down. The result is cleaner water, stronger biology, and more vivid coral coloration. Explore more reef additives and supplements.

What Reef Actif Does

• Made from natural marine biopolymers of algae and plants
• Adsorbs excess nutrients and pollutants from the water
• Feeds beneficial bacteria as a prebiotic, boosting their activity
• Promotes vivid coloration in corals and clams
• Supports fish health and natural behavior
• Keeps protein skimming consistent and parameters steady between water changes
• Formulated for saltwater and reef aquariums only

How To Use

Add one measuring spoon per 500 liters, about 132 gallons, once per week. Dissolve the powder in a small amount of aquarium water first, then distribute it around the tank. You can dose up to three times per week at the same concentration if you want a stronger effect. Reef Actif is compatible with the other Tropic Marin Bio-Actif care products, so there is no risk of overdosing when they are used together.
