changing from brackish to fresh water?

I need some help transitioning three freshwater fish (an angel, a danio and some type of algea eater -I didn't get a good look at it) from a brackish water tank to a fresh water tank. My nephew knew how to keep the tank clean (the brackish one) and keep the fish alive, but he passed away recently. I want to convert the tank to fresh water for his younger brother if I can so he can care for them easier.

Would changing out small amounts of water and replacing it with fresh water over a period of months so that the salinity decreases slowly work? I've got no idea how to maintain it in its present state, nothing was written down and, since I know you have to change out water for water quality sake, have no idea how to keep it brackish.

I've had a fresh water aquarium for over 10 years with minimal fish loss. I even have an original pleco that was in my original tank. If his brother doesn't want the fish I've asked to take them and incorporate them into my tank, but I don't want them to die either.

Any suggestions?

Update:

Oh and his brother is only 8 so I'm sure he isn't going to be skilled enough to maintain salinity at a constant level. That is a good suggestion that I can make to his mom though. Cleaning the tank would be a chore for him I think, even if it were only fresh water. I am going to try my hardest to teach him how to maintain it since he seems interested in it though.

    Your idea is good.

    Change small amounts of the water out and add freshwater, eventually you'll dilute the salt to the point where it will be basically freshwater. Be careful to do it slowly though!

    However, really brackish water isn't mush harder than freshwater. I suspect your nephew had a hydrometer to measure salinity? Once you have that and some kinda of synthetic marine salt your basically set for brackish.

    When you change the water in a brackish tank you just have to make sure you get the salinity of the new water the same as the old water before you put it in. Other than that its basically the same as care for freshwater.

    learn the various varieties of fish you have and what sort of water they desire. Do your guy or woman homework. i've got been lie to various circumstances with the aid of suggestion from puppy shop workers. (No offense.)
