Can anyone recommend a good book on maintaining a fish pond? I inherited
a
1500 gallon pond stocked with Koi when I bought my home recently.

Also, I'm having trouble keeping the pump going. The filter clogs after
about 2 hours of use, and has to be cleaned. Do I need to change the
water
in the pond, or treat the water?
