Oscars (Astronotus ocellatus) come originally from the Amazon area where the water is very pure and contains almost no salt at all. Adding salt to their water will do them no good but may well damage them.
The moisture content and or humidity can and will cause some items to rust or corrode. The salt content of the water should have little effect -- salt levels are not high enough. k
high salt content prevents plants from absorbing the water
Salt content is not affected by temperature. +++++++++Next post by different person++++++++++++++++++++++++++++++ Yes the salt reading will be off when water temperatures drop below 60
I don't know. My best guess is that they would taste horrible just like saltwater from the oceans because of their extremely high salt concentration. Salt water pools are less than 1/5 the salt of the ocean. The salt content mirrors the salt content of our bodies. The taste is very mild. Chlorine levels will vary. The pH and alkalinity of the water have an effect on bather comfort.
homeostasis does have salt effect, when you sweat you lose water and salt
Ocean water has a higher salinity (salt content) than fresh water does.
Give a higher density to the water due to the salt content which causes object to float higher.

because of salt content water is saline
Salt water can cure a scratchy throat

because, the dead sea gets it's name from the high amounts of salt to water content, when this high salt content water washes up on shores, it creates salt dunes
