### ⭐ 1.0 out of 5 stars







  
  
    DI Resin was mostly amber when received and ran out after only 30 gallons of water
  

*by M***E on Reviewed in the United States on February 3, 2019*

When I received the cartridge the resin inside was already more than 50% amber, which should have been a red flag and caused me to return it immediately, but I needed to get my RODI up and running for my coral reef tank so I couldn't really afford to wait for a replacement. Now I wish I had, since the DI is almost completely amber now after only ~30 gallons of water and it is now showing 1ppm on my in-line TDS meter instead of the expected 0. The TDS from the membrane, before the DI chamber, is only 2 and is consistently only 2, so this was just a bad batch of resin. Very disappointed.
