Then took the jug out and repeated the same process for the top half.
My rough guess would be about 150 grams of salt in 2 L of water.

Are you sure you saturated the mix? (kept going until it wouldn't dissolve more)
https://en.wikipedia.org/wiki/Saline...20(%25%20w%2Fw).
According to this, to saturate, room temp water can dissolve around 357g of salt per litre. Are you sure you got it until you couldn't dissolve any more? I just want to clarify the almost a 4x difference in salt according to the link above based on my napkin math.
I mean, salt is pretty cheap, so to saturate a 4L bottle, I think it'd only cost like 3-4 bucks for a big bag of the cheap ionized salt that is required.
This salt water discussion is making me feel like making slushies with the kids this weekend.
