Smelly water from fresh water tank
My boat has a 100 gallon aluminum fresh water tank. A month ago, when we put it back in the water, we filled, drained and re-filled the tank. When we went down to the boat this weekend, the water had a strong sulfer like smell. I assume that this is related to bacteria or other life in the water. I''m going to add a two stage filter to part of the fresh water system, but would appreciate suggestions on how to avoid the problem. I thought of putting a little chlorine in the water, but supposedly that is a bad idea with an aluminum tank. It has been suggested that I add a little iodine. Any suggestions would be appreciated.
