Answer 1

you could do that but first you have to let the water filter through for a bit then add some anti-chlorine or other bacteria fighting agent.

Answer 2

For cold water /normal river/pond fish ,it is ok,at least it wont have the acids and other materials in it that farmers use on the land.You must aerate it though or it will stagnate.

Answer 3

you can use the same but do keep next to tank for 30 mins b4 mixing in tank. let the water sttle down than filter it and mix
