I'd sanitize the system and replace the filter. You may have green slime growing in the fresh tank and it may take several filters to clear it. I also think I'd add a bit of chlorine to the water when you fill with the well water. Remember, well water is not treated and can quickly grow yuck in a closed dark system.
If you can fill with city water, I believe I'd do that instead of depending on well water.
