As we have already mentioned, it is really essential that
you do have a selection of good bowls - from the small 18"
diameter ones up to perhaps, depending on the size of your
largest Koi, 28" or 31".
Bowls should always be cleaned out thoroughly after use and
remember to do this every time .. it is no use grabbing a dirty
and possibly contaminated bowl when you urgently need one as you
will not have time to clean it before you put this in use again
.. So it is another good rule to bear in mind .. clean the bowls
