For use with the IonGen G2 System, the Aquascape IonGen replacement probe helps deflect debris and reduce clogging to ensure proper functionality. The IonGen system effectively kills algae without the use of traditional liquid chemicals. As copper ions are added to the water, the probe is consumed. Aquascape recommends that the IonGen probe be replaced annually to remain most effective. The IonGen Probe for the G2 System is specially designed to fit the 2nd Generation IonGen Flow Chamber, allowing for a tool-free probe installation and trouble-free use. The included 5-foot quick-connect cable makes installation simple and easy. Aquascape is passionate about the products we produce, providing unique products, designs, and features that stand above the competition.
