ATM's Agent Green Phosphate Remover is designed for maximum performance and efficiency in removing phosphates instantly. Agent Green acts as an ion exchanger that uses calcium to bind phosphate into insoluble beads. This is critical primarily because the phosphate will not dissolve right back into the water while waiting to be swept out by filtration.
Agent Green features a professional lanthanum chloride formula that is reef safe. Keep dangerous phosphates out with instant-acting Agent Green.
