Regenerable Aquarium Filtration Resin for Freshwater and Saltwater Tanks, 100 or 500 ml – Seachem Purigen
Regenerable Aquarium Filtration Resin for Freshwater and Saltwater Tanks, 100 or 500 ml – Seachem Purigen
Regenerable aquarium filtration resin removes nitrogenous organic waste before it breaks down into ammonia, nitrite, and nitrate. Seachem Purigen uses a premium synthetic polymer adsorbent for freshwater or saltwater systems, helping polish water clarity while having minimal stated impact on trace elements. The pale resin progressively darkens toward brown or nearly black as it becomes exhausted, giving aquarists a visible cue to service the media.
Choose 100 or 500 milliliters according to the aquarium volume and filter configuration, then place and use the granules only as directed on the product label. Purigen can be regenerated after exhaustion, but the process involves bleach and requires exact chemical handling, rinsing, dechlorination, and safety steps. Never improvise a ratio, mix bleach with other cleaners, or return incompletely regenerated media to livestock. Replace the resin when regeneration is unsuitable or the material no longer performs as expected.

Frequently Asked Questions
What does Seachem Purigen remove?
Purigen adsorbs nitrogenous organic waste before that waste can release ammonia, nitrite, and nitrate into aquarium water.
Can I use it in both freshwater and saltwater tanks?
Yes. Seachem identifies Purigen resin for freshwater and marine aquarium filtration systems.
How can I tell when the resin is exhausted?
The granules darken from pale blonde toward dark brown or nearly black as they adsorb waste and approach exhaustion.
Can Purigen be regenerated safely at home?
It is designed for regeneration, but the process uses bleach and requires the exact label steps for chemical safety, rinsing, and dechlorination. Never improvise.
