75gpd system with one poly, two carbon, RO, DI. Purchased from BWI (Blue Water Irrigation, Canadian supplier). I've had the system since mid April this year and have produced 242 gal RO/DI, 32 gal RO for a total of 274 gal. DI media is starting to change colour at the bottom, less than 1/4 of the way up the cartridge I reckon. Haven't changed any cartridge/media yet.
