I'm sure others with more experience will expand upon this, the larger the tank the better off you'll be for salt water. Personally, 90gal, 120gal, or even 180 gal would be good. well you can use 20, or 30 thirty to quarentine before adding to a larger tank.You will find most species need at least 55 some only 30, so at least 30 No less than 55 is recommended, 1inch per gallon
Fish Only: 72°F - 74°F [22.2°C - 23.3°C]
Fish Only With Live Rock (FOWLER): 74°F - 78°F [23.3°C - 25.5°C]
Reef : 72°F - 80°F [22.2°C - 26.6°C]
Note: Check with your fish supplier for exact needs, these are only approximate temperatures. Reef's should only be kept by experienced personal as differentness corals and fish require different temperatures. The most common available Saltwater Fish with thrive in the temperatures listed above.
Most people would use something in the 80-120L size for a sump for a tank of that size.
Personally, I think fresh water is easier because a salt water tank means that you need to purchase aquarium salt, and you need to add it to every water change. I have never raised a saltwater aquarium, but I believe you also have to measure the amount of salt the fish need. So if you're a first-timer, go for the fresh water tank. But the good thing about saltwater tanks is that it is more diverse and colorful.
the salt comes with a scoop and 1 per gal of water is what I do and it has worked great for me
It is not recommended to mix salt water fish and fresh water fish. It is required to separate the two and provide each with the proper tempered water.

A minimal tank size of 2.5 gallons is recommended for a single Betta fish.
Epoxy is a near perfect water barrier. This applies to salt water as well. As the epoxy coated tank and the salt water does not contact, the corrosion does not occur.
i dont really know sorry
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.
That depends, of course, on the size of the tank and what you put in it. A small tank such as a nano tank or a pico tank, is not too expensive to keep up. There are many corals you can have without spending an arm and a leg. Also some people have fish only which in general is less expensive. The salt water can be purchased or made at home. You needs light which can be very expensive for LED units or much less reasonable if you purchase lights such as T5s . It is possible to own a salt water tank and not spend a fortune keeping it up.
no
The simple answer is yes.
