Emily:
I forgot to ask, what type of tds monitor do you have?., I have the Milwaukee which is suppose to be calibrated at the manufacturer.
Any idea how I'm suppose to know if calibration is needed?, I guess a reading of 21 for Calgary tap water is a pretty good indication, considering your reading is much much higher.
How much did Western Pump charge for calibration, also do they sell the sediment filters & the 1 micron carbon Blocks?
Thanks
