Is there such thing as a SG Shock?

Isn't there such thing as SG shock? Similiar to a pH shock or temperture shock when they are changed too rapidly?

Not going down.

If you transfer the fish quickly you'll have problems. A drip acclimation over a few hours will work but I prefer to slowly raise the SG of the QT tank to 1.018 over a week or so and then do the drip.

I see.
Just to make sure here. So you mean when I get a new fish I can really just. more or less, dump it right into a QT with a SG of around 1.010-1.013, which is pretty much hyposlainity? But when I move it to the display the process of going to higher SG has to be slow?
I read about going down is okay but going up is troublesome because it causes dehydration. Is that why?

Yep you really can just drop them in to a lower salinity like that, doesn't seem to bother them. I don't really know why going up is more problematic, it's more of an immediate shock than just dehydration. I've seen it and it's bad.

Okay thanks!
I think I will really give this a try. Since I'm likely getting a Tang as my next fish.
