Phosphate Out Pro is a new, higher capacity phosphate remover for aquarium use that is made of the highest capacity granular ferric oxide (GFO) currently available. It’s been a few years since the release of the original AquaMaxx Phosphate Out and the Pro formula allows for even more phosphate removing potential, or less frequent replacement in lower nutrient systems.
Despite being twice as effective at removing those dreaded phosphates, Phosphate Out Pro is only 50% more expensive than its regular counterpart. Where a single quart of Phosphate Out retails for around $19.99, a quart of Phosphate Out Pro will set you back $30.99. [AquaMaxx]
