[Q] How to remove Hydrogen sulfide from well water

I am trying to start back up my aquarium fish collecting and breeding business. One obstacle is the well water I have to use. Raw it is full of iron sulfates and hydrogen sulfide, and other noxious chemicals. If the raw well water is left to sit it goes from a being a thick green to being red orange and red orange mud settles onto the bottom. Once I run it through water a softener system it comes out clear and very soft but still full of hydrogen sulfide and almost totally anoxic. I need to be able to remove the H2S and add oxygen. I have thought of using H2O2 to add oxygen but will this also remove the H2S?
