Can’t taste the media in my drinking water. Works as advertised. ### ⭐⭐⭐⭐⭐ Works great. *by M***L on April 26, 2021* Great quality stuff and probably the best value out there. ### ⭐⭐⭐⭐⭐ Save $ by refilling *by N***H on February 25, 2019* The resin allows me to refill my DI cartridge at half the cost to replace. I use it in AquaFX barracuda, but it will work on any refillable cartridge, ones that the bottom screws off. Simply unscrew the bottom, trach the old resin, rinse well and refill with this bag. The bag was a perfect size to refill once. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/44479919-kolar-labs-di-color-changing-deionization-resin-for-fish-tanks](https://www.desertcart.gr/products/44479919-kolar-labs-di-color-changing-deionization-resin-for-fish-tanks) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
