I would say that it would depend on the specie. You should spot clean feaces as soon as you see it so a full clean out could probably be done once a week maybe a bit longer
Enough salt and it will kill the fish
If you are premixing the salt in a large container outside the tank, then put the sand in first. If you are going to mix the water and salt in the tank, then put the water in and mix it first, and then when its mixed put in the (rinsed!) sand. It will fog up, but that will go away.
no
put regular water in and and put your own amount of salt in it so it won't be a lot of salt
No
they will die
Salt is often put on the sidewalk during or after it snows. This is because salt lowers the freezing point of ice. This is often just enough to melt snow at subfreezing temperatures.

Salt Water Fish
Yes and No because the snake may or may not be healty and if anything get a salt water fish tank because if you let salt water let it soak there for 2-3 days,then dump the water out. Then put salt water in and any fish you would like.
Drinking water tank NONE unless you want your horse to get diarhea, sick and dehydrated
Aquarium conditioning salt at a level of about 0.20% is safe for your betta, so you can immediately put your fish back in the tank. If you think you may have put too much salt in, use a salinity test to check your tank and make adjustments if necessary before putting your betta back in.
