Towns listed on the above website are under a boil only order for the time being and the mwra's regular water source has been changed to the relatively un-managed Cambridge reservoir and spot pond.

This could affect your fish negatively if you perform any water changes: The water is likely to contain more contaminants then regular drinking water, and ph, hardness, and other parameters may be different than usual due to the new water source.

AT minimum, you should barrel your water and prefilter with high grade carbon before performing water changes. At most, use spring water or refrain from changing tanks until the water main is fixed.
