Description

Colour Changing DI Resin Refill

This Colour Changing DI Resin Refill contains 1.25 lbs of Deionization Resin  which is sufficient to fill a 10 inch refill cartridge. The RO/DI system has become an essential component of successful marine aquariums. In order to reduce Total Dissolved Solids (TDS) to zero the RO water is passed through the DI resin which removes any remaining impurities in the water.  Optimal use of the resin is dependent on the rejection rate of the membrane. A healthy membrane is maintained by monitoring and changing your pre-filters appropriately as well as maintain at least 50psi going into the membrane. Colour changing DI Resin will physically change colour to yellow as it becomes exhausted, allowing you to monitor the consumption of the DI resin and know when to change it out.  We recommend testing the TDS before and after the DI Resin to ensure its effectiveness and display early signs of the TDS creeping up through the DI resin. To maximise the life of the resin you should take the following steps:

  • Ensure the resin is packed very tightly in the cartridge so that when squeezed, there should be no flexing.
  • When the RO/DI unit starts the RO membrane often produces high TDS for the first few minutes so we recommend diverting this water down the drain.
  • Maintain low levels of carbon dioxide in your water supply as this will deplete DI resin more quickly.
