View Full Version : 35ppt refrac calibration fluid

Anyone have 35ppt calibration fluid. I purchased the red sea refrac and calibrated on distilled water at 0ppt and it read my salinity at 1.021. swingarm is 1.025. I want to double check the refractometer so i can get the salinity correct.

Thanks kj. I placed an order on BRS and grabbed a couple bottles.
