Your guess is as good as mine. Possible? Probable? I honestly don't know. I would guess the next step is to find out what the suspended particles are that make your water muddy. It could be a natural imbalance of limited minerals/nutrients? To correct the balance, nature moves to larger particulate that doesn't readily dissolve.
I think you have reached the apex of my insight into your issue?
Maybe pour some of your water through a coffee filter and find out what the suspended particles are? Then it might be possible to trace the source or the issue?
