Salifert Extrax Phos is an advanced adsorption media designed to rapidly remove phosphate and silicate from both saltwater and freshwater aquariums. It acts quickly to lower unwanted nutrients, which are a primary cause of nuisance algae, helping to create a cleaner and healthier aquatic environment. Using Extrax Phos is a crucial step in a sensible nutrient-control program for any high-performance reef or planted aquarium.

The media's unique spherical shape is engineered for maximum efficiency, providing a vast surface area that enhances reactivity and contact time with aquarium water, outperforming many non-spherical competitors. It is completely safe for all aquarium inhabitants, including sensitive corals and invertebrates, and will not release absorbed phosphate or silicate back into the water column once exhausted. For best results, the media should be rinsed in purified freshwater before its initial use.

This product is ideal for aquarists struggling with persistent algae issues or who need to maintain ultra-low nutrient levels in demanding reef systems. Whether you are battling a sudden phosphate spike or implementing a long-term maintenance strategy, Extrax Phos provides a reliable and powerful solution. It allows for precise control over water chemistry, ensuring your corals display their best colors and your tank remains pristine.
