Review on Avanti Color Changing Inline Deionization ResinTech by Julie Nelson

When I received the cartridge that was it Resin already over 50% amber internal which should have alerted me and returned immediately, but I needed to set up and run RODI for my coral reef tank so couldn't afford to wait for a replacement. Now I wish I had as the DI is now almost completely amber after only 30 gallons of water and is now reading 1ppm on my built in TDS meter instead of the expected 0. TDS from membrane to DI chamber only 2 and only 2 consistently, so it was just a bad batch of resin. Very disappointed.
