Question re: replacing the carbon in RO/DI filter
I have had my tank running for one year now. My RO/DI seems to be running very well as my TDS meter registers ~ 180 going in and 0 ppm going out. So ,my question, should I still be changing the sediment and carbon every 6 months no matter what the TDS meter registers?
And being a year, should the DI be changed as well?
Many thanksl
