Keep your IonGen™ System G2 running efficiently with the Aquascape IonGen™ Probe for the G2 System. This specially designed probe allows for quick, tool-free installation, with a 5' quick-connect cable making setup a breeze. The IonGen™ System G2 uses copper ions to kill algae without the need for traditional liquid chemicals, and will eventually consume the probe. Keep your system functioning properly with this replacement probe.
