Hey reefers, I think my TDS meter needs to be recalibrated. It says on the back that it requires NaCl. Does anyone have this fluid or know how to recalibrate a TDS meter?
hey andrew,
i got the tds calibration fluid. i'll have to check if it's nacl. haven't had to calibrate mine yet so i don't know how to do it but....i got the reference fluid. i'll bring it by this sat. if we don't get major snow.
