I had been using the Kent Marine pre-packaged DI cart and had not been extremely happy with its performance. To replace the resin I had ordered the refillable unit from The Filter Guys. I am presently using two DI carts after a CTA RO unit, yes I know CTA aren't great with rejection rates but my TFC 75 GPD unit will be here Monday. Is anyone else using TFG's resin? Even after running the water through two DI my TDS is around 0.65. I am also looking into getting a new hand-held TDS meter as the one I have can not be calibrated and I am not sure if it is the water or the meter.
Are there any other places that have good bulk DI resins I could look into? I am not against prefilled carts just haven't found a good one yet.
