Where are you filling your tank from ?? A well may have more contaminants in it then a public water system causing the problem to come back.
We have that problem on our outside tank that we use for filling the agriculture sprayer but, it sets outside in the sun. I've never seen a tank in a TT that bad because they are mounted where it's dark.
I fill from a city water supply, and have for years, but I am the second owner and don't know where the previous owner got his water. The bottom of my rv is not enclosed, so the tank gets lots of indirect sunlight.
