Hello all,

I've read many threads about Koi needing to have crystal clean water in order to thrive. Then I
looked at a few websites for Koi breeders in Japan, and their Koi live in mud ponds and the water is
far from crystal clear. Look at these pics -

Now... these breeders have zillions of dollars (yen) invested in their Koi, so they need them to
maintain prime health. This being the case, is it really necessary to have clear water for koi? Yes,
Ph, nitrates, nitrites, and such need to be correct - but it seems the water itself does not need to
be clear.

What am I missing here????
