Fauna Marin Ultra Phos is a high-performance, aluminium-based filter medium designed for the rapid and effective removal of phosphates (PO4), silicates (SiO2), and organic pollutants from both marine and freshwater aquariums. Unlike iron-based adsorbers (GFO), Ultra Phos works with exceptional speed and remains effective even in systems with extremely high nutrient levels. Its unique surface structure ensures that once pollutants are bound, they are not released back into the water column, providing a reliable solution for maintaining the ultra-low nutrient levels required for sensitive stony corals and preventing nuisance algae outbreaks.
Ultra Phos provides a powerful tool for aquarists needing immediate control over rising phosphate levels.
Aggressive Phosphate Removal: Highly effective at lowering phosphate levels quickly, making it ideal for newly set up tanks or systems experiencing a sudden nutrient spike.
Silicate Control: Effectively binds silicates to prevent the growth of brown diatom algae, ensuring glass and rockwork remain clean.
High Binding Capacity: The specialized aluminium oxide structure offers a massive internal surface area, allowing it to hold more pollutants per gram than many standard media.
Does Not Release Toxins: Engineered to be extremely stable; it will not leach aluminium or bound phosphates back into the aquarium even as the media becomes saturated.
Improved Light Penetration: Removes yellowing substances and organic tint from the water, significantly improving water clarity and coral light absorption.
How should I use Fauna Marin Ultra Phos? It is best used in a fluidized media reactor or a mesh filter bag placed in a high-flow area of the sump. Before use, rinse the media briefly with RO/DI water to remove any fine dust.
How much should I dose? The recommended starting dose is 50 ml of Ultra Phos per 100 Liters (26 US gal) of aquarium water. If phosphate levels remain high after 5 days, the dose can be increased up to 100 ml per 100 L.
How long does the media last? The lifespan depends on the nutrient load of your tank. Once your phosphate levels begin to rise again, it is an indication that the media is saturated and needs to be replaced.
Can it affect my corals if the levels drop too fast? Yes. Because Ultra Phos is very aggressive, a rapid drop in phosphate can stress corals. It is recommended to monitor your levels daily and start with a smaller dose if your corals appear sensitive.
Fauna Marin Carb L: High-purity activated carbon to use alongside Ultra Phos for total chemical filtration and crystal-clear water.
