- What does this media actually remove?
- It is a chemical filter resin, so it targets dissolved organics, discoloration and leftover medication rather than particles or ammonia. Pair it with sponge or ceramic media for mechanical and biological filtration.
- How much media do I get?
- Two bags of 300 ml each, 600 ml total. Check your filter's media tray volume before buying; large canisters often take a liter or more.
- How often do I replace it?
- Resin is spent when water color returns or after a set interval, typically a few weeks to a couple of months depending on load. The listing does not state a replacement schedule, so follow your filter maker's guidance.
- Can I use it in a freshwater tank with shrimp?
- Chemical resins are generally safe in freshwater, but confirm the resin type before use with invertebrates. Do not run it during a copper treatment you want to keep in the water.
- Is $15.99 a good price?
- It is the only new price listed as of November 4, 2026, at Amazon, so there is no lower recent price to compare. Compare cost per 100 ml against other bagged resins before deciding.
