After swapping it in, my TDS immediately dropped back to 0 and has stayed there consistently through several water batches. The cartridge was well-packed, sealed tightly, and fit perfectly into my canister — no leaks or loose fittings. The resin itself looks fresh and evenly packed, not dried out like some cheaper replacements. It’s easy to install and makes a noticeable difference in water clarity and coral health over time. Pro tip: keep a handheld TDS meter handy and change cartridges when you start reading 1–2 ppm — that’s how you know it’s time. This DI resin cartridge gives the same performance as name brands but at a much better price. Highly recommend for anyone maintaining a reef tank or using RO/DI for top-off water. Review: Poor quality and not worth the money! Don’t buy! - Don’t waste your money. Poor quality not full of resin and packed tightly. Also they leak and there is no way to get the seal set properly in place. I wish I could get my money back. Pure crap!!! ## Features - 💧 Reduces Total Dissolved Solids (TDS) to "0" : The deionization resin is necessary to reduce Total Dissolved Solids (TDS) to zero in the final stage of an RO/DI system.
