Do these parameter values seem reasonable?
Just got a TDS meter and tested it out with a different water samples, along with GH, KH, and pH (also from a new meter).
Note, I tested the TDS with the meter yesterday before doing a ~40% water change with 1/2 RO-1/2 Tap and it was right at 200 ppm.
Was worried about tap water being too hard and/or alkaline, but it's looking like its right on the money honestly.
Edit: guess I was asking whether the TDS reading for the RO water was reasonable. Seems way off the charts.
