New to the Reef Keeping Industry are the Skimz Macroalgae Reactors. These reactors are a valuable and necessary form of filtration for any reef tank. Whether you're working with restricted space and don't have room for a sump, or you're looking to add the additional benefits of natural macroalgae filtration, Skimz Macroalgae Reactors are right for almost every tank. Water is carried into the reactor where Macroalgae is stored, while the built in LED Lights keep your Macroalgae thriving to remove harmful compounds such as Nitrates and Phosphates. The Skimz Macroalgae Reactor packs all these features into the sturdy construction of every Skimz product; which is why we carry them here at Reef2Land. Should you have any further questions don't hesitate to contact us.
