hey, is anyone around today to help me double check some salinity readings. i received 2 packets of 35PPT SALINITY CALIBRATION SACHET hanna from bulk reef. checking my refractometer, with fluid at 77 deg, it read 22 or so. adjusted to 35 per packet, opened the second packet, read 35. now my water reads like 42 and ro reads 12. my guess is the packets could be off ?? is it possible i ran my tank 12ppt high, in the 40s. seems unlikely. these are not recent builds and the refractometer is not new. thoughts, or opinions here ?? thanks. have transportation and time, willing to travel. lol thanks!! my mixing brute is a 44 i think, per height and width, and i use less than 1 50g salt bag for 35ppt. found my hydrometer and compared my mixed up water, lets call it 1.026 thats much closer to my ro/di calibration reference, compared to my 42ppt after the calibration fluid.
