I doubt it. I think you have water in your tank because it's no way how antifreeze can go in your tank unless you puuted it there. So if you have water in your tank, just buy stuff which is called dry gas. And everytime when you fill your tank add required quantity. To get rid of water in your tank you will need to do that at least 3 times, it depends on how much of water you have.
