Purigen

🧪 Usage Instructions

Initial Setup (First-time use):

• Rinse thoroughly before placing in the tank.
• Dosage: Use 250 mL of Purigen for up to 1,000 L (264 US gallons) of water.
• Place in a fine mesh filter bag in a high-flow area (e.g., canister filter, sump, or HOB).
• Will darken as it absorbs impurities—this is normal.

Maintenance Dosing (Regeneration):

• Regenerate when color turns dark brown/black.
• Soak in a 1:1 bleach:water solution for 24 hours in a non-metal container.
• Rinse well, then soak in a solution of dechlorinator (like Seachem Prime or Safe) for 8 hours before reuse.
• Do not use if it still smells of chlorine—repeat the rinse/dechlorination if necessary.

Frequently Asked Questions (FAQ)

Q: How is Purigen different from carbon or other resins?
A: Unlike carbon, Purigen specifically targets organic waste, does not remove trace elements, and is regenerable, making it more efficient and economical.

Q: How do I know when it’s exhausted?
A: Purigen will turn dark brown or black when saturated. This signals it’s time to regenerate.

Q: Is it safe for reef or planted tanks?
A: Yes! Purigen is reef-safe and plant-friendly—it won’t remove trace minerals or beneficial nutrients.

Q: Can I regenerate Purigen indefinitely?
A: While Purigen can be regenerated multiple times, it will eventually lose capacity. Replace once it fails to lighten after regeneration.

Q: Can I use Purigen with other Seachem media like Matrix or PhosGuard?
A: Absolutely! Purigen works perfectly alongside Matrix, PhosBond, PhosGuard, and MatrixCarbon.
