There can be bad batches. Just like there can be bad reagents for test kits. First post states this should be for those times where things are going well to get a general idea of what to expect from a particular salt brand. A bad batch is not something to expect on average.
I tested Instant Ocean Regular again today to be sure that the results I provided were accurate.
I used a Marine Depot Refractometor PRO calibrated with Aqua Craft Refractometer Calibration Fluid from BRS @ 35ppt 1.026sg.
Alkalinity 10.36dKH Hanna Checker verified by Salifert
Calcium 370 Salifert verified by API, and Red Sea +/-10
Magnesium 930 Salifert verified by another Salifert test kit and Red Sea
The salt was purchased this week from Drs Foster and Smith with lot#16103.
I purchase from large suppliers that keep their salt constantly moving compared to a private vendor on Amazon or Ebay that can have an old batch sitting for a while before being sold. I have purchased all of the salts I have tested from Drs Foster & Smith, Bulk Reef Supply, and Marine Depot.
If there is a way of verifying a bad Instant Ocean batch please let me know.
