As far as swordtails mollies guppies and plates, should aquarium salt be used, I have herd different stories some say it is not needed. If needed how much should be used in 10 gallon tank.

I too have heard conflicting ideas, this is what I have come up with. Wild caught mollies need salt. Otherwise they have been bred in aquaria so long they no longer need the salt. As far as I know Guppies and Platys don't need salt at all. I have guppies and platys both and they do very well with out. When I kept Mollys i never put salt in their tanks.
