It depends on how many fish you have and the quality of your filtration system. In lightly stocked tanks, I would recommend changing 10 percent of the water once a week. You could probably get by with vacuuming the gravel once every two weeks depending on the population of your tank. Heavier stocked tanks will need larger (25% or more) weekly water changes and gravel vacuuming.

Maybe - first test for chlorine and/or chloramine. Most likely you will have these chemicals in your water and you will need to remove or neutralize them before adding water to your tank.
