We recommend changing your resin when the TDS (total dissolved solids) of the water is higher than 10 ppm (parts per million)(You can check this with a TDS meter).
Please Note:
- Resin sold by the litre will be shipped in clear zip-lock bags and is recommended for immediate use/change as the clear bags are not ideal for long-term storage of the resin.
- We recommend storing the resin in an airtight container in an area that doesn't fluctuate in temperature causing condensation in the container. This will help prolong the life of the resin while in storage.
