Calibration button is on the right bottom in Smart reef in TDS mater panel.
To calibrate TDS meter you need to have 000 TDS RO water. If you have no 000 TDS water then the easiest way is to exchange resign in filter (you need good quality resign for instance Triton Di). If you replaced resign in your filter then swich on the whole Reverse Osmosis filter and wait arround 10 minutes. Then click “calibrate button” in Smart reef.
