I am getting a lot of natural gas and h2s in my well water, a casing leak in a nearby oil well is the culprit. I want to install a tank to oxidize the water and release the gas prior to the pressure tank. I contacted the only water well "expert" in my area, I live in a very isolated part of south west texas, and got very little advice. I understand the construction of the system but I need to know what size and type of tank I need.
