I diluted by 50% with RO and tested again, got 1000 flashing, indicating too low range. I tested again and diluted by .33% and got a reading of 1100ppm. Did the math and came up with 1650 for my result. Not sure why the first test blinked 1800 (over range) if it is sitting at 1650. Gonna do a full strength test again tomorrow.

Not a promising set of results. lol
