The IO Series Ionizers deliver clean, clear, healthy water by electronically releasing metal ions into the water. Ionization will dramatically reduce maintenance on any pond or water feature. The energy efficient electronic controllers allows for complete control and adjustment of the ion levels in the water feature. The ionizers use anodes that can be easily replaced and typically last 1-3 seasons, depending on water quality and usage. Ionizers can be quickly and easily installed on nearly every pond or water feature.
