Nyos Aqua Pure Aquarium Treatment, 1000-mL jar

When placed in a filter behind your tank’s reverse osmosis system, Nyos Aqua Pure Aquarium Treatment can help to create pure output water. It helps to remove any ions that the reverse osmosis system may leave behind, including bad stuff like silicates, nitrates, phosphates and heavy metals. Using Aqua Pure regularly can help to prevent planaria, diatoms and red algae, making for a healthier aquarium. Since it’s so absorbent, Aqua Pure is a highly economical way to support clean, pure water.
