Controlled Phosphate Reduction Without Risking Nutrient Starvation

Fauna Marin Phos 0.04 offers a safe, highly effective approach to phosphate and water clarity management in reef aquariums. Traditional phosphate removers can strip water too aggressively, causing sudden drops to 0.00 mg/L that stress or bleach sensitive corals. This specialized compound granulate eliminates that risk while maintaining low, stable nutrient parameters.

Key Benefits

1. Safe Reduction Down to 0.04 mg/L

Unlike conventional adsorbers, Fauna Marin Phos 0.04 is engineered so that phosphate concentrations cannot fall to 0.00 mg/L. This unique property ensures safe, controlled nutrient reduction while remaining highly effective at lowering excess PO4.

2. Permanent Binding with Zero Re-Release

Once absorbed, phosphates and organic yellow substances remain tightly bound to the granulate structure and are never released back into the aquarium cycle. This keeps water crystal-clear and maintains a consistently low nutrient environment.

3. Prevents Nuisance Algae & Enhances Coral Coloration

By removing excess phosphates and yellowing compounds, Phos 0.04 starves unwanted algae growth and improves light penetration, creating ideal conditions for corals to express their full, natural color pigmentation.

Dosage & Application Directions

1. Initial Dosage: Use 50 ml per 100 liters (26 US gal) of aquarium water.

2. Dosage Increase: After 5 days, you can increase the dosage to 100 ml per 100 liters (26 US gal).

3. Monitoring & Replacement: Check PO4 values regularly with a reliable aquarium test kit. Once phosphate levels start to rise again, replace the exhausted Phos 0.04 media with fresh granulate.

HeldeReef Tip: If your PO4 is currently very high, use a more affordable bulk remover—such as Ocean Six PhosX, Orca Phospha-Guard GFH DARK-ICE, or similar—to bring your initial phosphates down first, then switch to Fauna Marin Phos 0.04 to maintain stability and keep your phosphates from bottoming out.
