The tank needs to be filled to within an inch of the top. As well as having a cycled filter running you will also need to replace 50% of the water weekly if you wish to keep your fish healthy.
The cells of the saltwater fish would gain too much water.

I have freshwater fish and i use aquarium salt. I put more in every time i do a water change

They're designed for salt water, not fresh water! Just the way they are made. You can get aquarium salt from your local pet store, but don't put any in there if you have other freshwater fish that don't need it. Or get a tropical freshwater fish like mollies instead!
If you have never set up a freshwater aquarium before, it would be best to call an expert. Check Yelp listings for some freshwater aquarium stores in your area. You will find reviews on them and choose which company is best for you.
If a saltwater plant were placed in freshwater aquarium then the plant cells would burst. This is because the salt water would make the plant cell allow more water to come in.
Depending on the type of fish, Freshwater or salt water. It also depends on the disease. I know that freshwater fish can have fungus on them. But I'm not sure about salt water.
