Pre-Mixing High Salinity Salt Water, has anyone done this

[Biglew11]

True, why didn't I think of that. But you think there is risk mixing at higher level?

Most salt mixes advise not making concentrated mixes because of precipitation that will not redissolve.

there are no loopholes. Just don’t do it.

the problem isn't the concentration of salt, it's the high levels of calcium and alkalinity. at normal levels they still want to precipitate, at higher levels the reaction happens much faster. and once it starts it's a self feeding snowball reaction.
