Invest in a TDS meter to check your purified water before using in your aquarium. **Q: Can this be used for frash water????** A: Yes it can be used on fresh water but only as part of a reverse osmosis filter.This media is not for filtering tank water it is for filtering impurities from tap water that is used to fill, top up or carryout water changes on your tank. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The item was in a well sealed and fresh *by V***A on 20 April 2026* yes this took out all the TDS out or water and left pure water with 0000.TDS works wonders ### ⭐⭐⭐⭐⭐ Great *by R***W on 13 February 2025* Product is great and came quickly. ### ⭐⭐⭐⭐⭐ TDS 26—0 *by J***B on 15 July 2025* Great resin and good price.
