> Dumping it back into the ocean can be disruptive to the local ecosystem.

I question this as being a problem. The ocean is saturated with the salts that are exposed on the sea floor. When there is too much salt in a solution, the excess will precipitate as solids. As the ocean is already exposed to more salt than it can put into solution, I don't think this would cause a serious issue.

Haven't heard of that before. Wouldn't it mean there are underwater areas carpeted in salt crystals?

It's been demonstrated as an actual problem with currently functioning desalinization operations.
