I was just thinking ...
after testing the tds of my rod I water
007 was the reason might be time to change do resin again as it’s only about 25% colour left .
I was wondering having a Hanna salinity pen that measures conductivity similar to a tds pen
With more tds does it effect the salinity reading making it not accurate ?
