I just bought a HM Com-100 TDS meter. I was curious and decided to check out the TDS of my tap water before I buy a RO/DI unit.
I have been using the DI tap water filter from Aquarium Pharmaceuticals only.
The TDS reading from the TAP was at 53 PPM using the 442 scale. and it was .4 PPM after the Tap water filter. Am i using the right scale? Does that sound right for NYC?
