I use auto top off with RO/DI.

I changed my carbon last week, and I don't add anything to my tank except pellets as good.

Is there anything I can test the water.

I did a TDS test on my NYC water vs my rodi using gone of those portable hanna meters..

NYC Water - 45
RO/DI - 125

What the heck? That's really strange. How can you tell if the meter is messed up?
