Keep your aquarium water balanced, clear, and algae-free.
Aquaforest Phosphate Minus is a highly efficient filtration media designed to reduce phosphate (PO₄) and silicate (SiO₂) levels in marine aquariums. Using advanced adsorption technology, it safely binds large amounts of phosphate without harming corals, fish, or beneficial bacteria — ensuring a stable and healthy reef environment.
Ideal for use in fluidized filters or filter socks, Phosphate Minus effectively prevents green algae blooms and cyanobacteria growth, supporting crystal-clear water and vibrant coral health.
🧪 Powerful Phosphate Removal: Rapidly binds and removes excess phosphates and silicates.
🌿 Prevents Algae Growth: Helps stop unwanted green algae and cyanobacteria.
🪸 Safe for All Aquariums: Gentle on fish, corals, and invertebrates.
💧 Stabilizes Water Chemistry: Supports long-term biological balance.
⚙️ Highly Efficient Media: Works perfectly in both fluidized and passive filter setups.
Dosage: Use 25–100 ml per 100 L (27 US gal) of water, depending on phosphate levels.
Setup: Place in a media reactor with a minimum flow rate of 400 L/h, or use passively in a filter sock.
Replacement: Change media every 4 weeks, or when phosphate levels rise noticeably.
Note: The media may slightly tint the water brown after initial use — this is normal and harmless. The coloration will disappear shortly.
Do not rinse before use — rinsing can reduce its phosphate removal efficiency.
