Our take on the IOAOI PuriResin Aquarium Filter Media, 100 ml, 5 Packs

IOAOI PuriResin is a spherical synthetic polymer filter media sold in 100 ml packs, listed here as a 5-pack. The beads are meant to sit in a filter or media bag and adsorb dissolved organics and impurities rather than host bacteria like ceramic or sponge media. At $15.99 at Amazon as of November 4, 2026, it is the only new price listed, so there is no recent range to compare against.

Questions and answers

How much PuriResin do I use per tank?
Dose by water volume, typically around 100 ml per small tank, and follow the pack instructions. The 5-pack gives you several doses or enough for a larger filter. Rinse the beads before use.
How long does it last before I replace it?
Polymer adsorbents usually exhaust in a few weeks to a couple of months depending on bioload. Replace or recharge when water clarity or odor stops improving. IOAOI does not publish a firm lifespan.
Can I use it with carbon or PuriGen?
Yes, but running two chemical media at once wastes capacity. Use PuriResin alone for polishing, or alternate it with carbon. Keep your biological media in place either way.
Will it clear cloudy or yellow water?
It targets dissolved organics that cause yellowing and odor, so it can help with tea-colored water. It will not fix bacterial blooms or particles; those need mechanical filtration and water changes.
Is $15.99 a good price?
Only Amazon lists it new at $15.99 as of November 4, 2026, so there is no competing price to judge against. Compare the per-100 ml cost with carbon or PuriGen before buying.
What is in the box?
The listing describes 100 ml packs sold as a 5-pack, though the spec fields disagree on item count and weight. Confirm the pack count on the product page before ordering.
Where is the IOAOI PuriResin Aquarium Filter Media, 100 ml, 5 Packs cheapest?
At Amazon, for $15.99, as of our latest check.
