For the advanced reef hobbyist with 3-stages of Deionization!  

NEW! AquaFX True 1:1 RO Membrane.

The Whale Shark takes water purification to another level. With seven stages of filtration, the Whale Shark produces the purist water for your reef aquarium. Three dedicated Deionization stages (Cation, Anion & Mix-Bed) captures every bit of impurity that may be in the water while allowing you to replace each individual DI resin separately. Water is prefiltered by a sediment filter and two Chlorine Guzzlers carbon block filters before being filtered by our True 1:1 RO Membrane. Our True 1:1 RO membrane saves you a ton of waste water while maintain the same high-rejection properties. Additional features include a manual flush kit and a ASO valve for convenient operation.
