FAQ: How should I store my Seachem Purigen® when not in use (i.e between regenerations)?

Purigen® needs to be stored in a small amount of water to keep the media moist. This will prevent the beads from drying out, which can cause them to shrink and crack, reducing the efficacy of the Purigen®. You may use R.O. or D.I water for storing the Purigen® or a small amount of tap (city) water. Any trace amount of chlorine in the tap water will not have an effect on the Purigen® and may keep undesirable bacteria from accumulating in your storage container.
