I rarely had this problem before, doing all as it should be done, dry mixing a salt is a bucket or a bad before using, still parameters are away from what they should be according to the manufacturer. Thought about bad batch or stored in improper place, bought another brand, the same. Third one, also needs adjustments for each mixing. Not for all of elements, then refractometer calibration would be a suspect. Mine is calibrated with TLF AccuraSea.
Salifert test kits, API as a back up. Salts: light blue bucket, uncommon highly recommended brand, Fritz RPM blue box, Aquaforest. Had no problems with Aquaforest before.
Am I missing something or just a bad luck, repeatedly? Changed test kits, the same.
