checked the specific gravity today and got 1.021 so i am going to add some more salt to get it up a littile more...what is the ideal specific gravity is it 1.024
Ideal is ocean...which is 1.026.... HOWEVER...the water in the tank evaporates but the salt remains. Each day the water line will drop, and you will have to add a little RO water to bring it back up to the correct water line. This is called "topping off". When the water line drops the SG rises because there is more salt than water when you read the last SG. By having your SG at 1.024 you allow some wiggle room so the SG will not rise too high. If you have an auto top off unit, then the water would be replaced as it evaporates and then you could set the SG at the exact ideal level.
