Marc Weiss Phosphate And Silicate Magnet

Removes Phosphates and Silicates from saltwater and freshwater aquariums . . Does not leach bound compounds back into the water. Can be used to pre-filter freshwater before mixing with marine mixPhosphate+Silicate Magnet is a sophisticated buffering agent that when applied binds phosphates and silicates that can cause undersirable effects in aquariums including increased algae and diatom growth. In time the bound compounds are broken down and used in subspecies metabolism.Ingredients: Iron, calcium, magnesium, selenium, molygdenum, copperDerived from ferment of: Sugar cane molasses, vitamins, yeasts minimize
