I have other clams and and the maxima also has sort of dulled in color.  It seem that the color most affected is the brown, so the zooxanthellea, but why???

 Brown is the color that absorbs light first. So definitely lighting would be my first thought. I don’t know how strong your desire is to try and change things, sometimes changes make it worse.
However if this is a good time to change your light bulbs I would try that first. And you are already on top of your water quality so lighting would be my choice.
I dont know though what K you have now and what K color to get in order to make it change to the original, because it would be impossible to duplicate the original conditions that clam was in.
