which water is good for any type of fishes?

Which water is good for an aquarium?
Tap water- used for drinking purpose, but mainly contains chlorine in it. Naturally soft
Well water- naturally hard, but contains bleaching in it.
If tap water is good then please tell me, which is the best product to remove chlorine, and how many drops shall I put in my 120liters of aquarium. OR

If well water is good, then mention the products used for softening of water and how to remove other toxic materials dissolved in these water which are dangerous for any type of fish.
Also tell me the cost of chlorine remover product and product for softening of water.

there is not a specific water perameter that works for all kinds of fish they all come from different parts of the world and have different requirements. as for treating water i would considder what the requirements for the species of fish i have weather they prefer soft or hard either way i would treat with prime it removes chlorine as well as detoxifies metals like copper. prime is dosed at 1 drop per gallon.
