Added too much salt... again

No amount of "science" could get me to throw out a brute can of fresh saltwater (not that that's what you all are recommending). Just get it to 35, test it, and adjust levels as needed

Correct, science does not say to throw it away. If it did, however, it might be foolish to use it. Remember the old commercial, “it’s not nice to fool Mother Nature”

Calcium carboante is supersaturated even at 35 ppt, and can precipitate. I mix Instant Ocean to 35 ppt and get this:

That's not been my experience. I have not gone much higher than 45ppt but I suspect I would have to go much higher to have that kind of precipitation on just a single mix. That crud looks like it was built up over multiple mixes.
