I saw the person I bought the Japanese butterflies from - he can't explain what happened. Too large a pond with too few fish to have a problem. He has given me the name of a local lab that can do pesticide testing. In his opinion, it has to be chemical contamination. I also spoke with the person who built the pond - he thinks pesticide drift from one of the neighbors. I'm calling the service both neighbors use and ask what they applied in the fall. The company owner knows I have a pond because I spoke to him about spraying trees on the property line.
Fred - the whole yard was landscaped around the ponds. I have an 1800 gallon in front for my topview ranchu and orandas. And then the 19,000 gallon for the koi. I designed the filtration system with the help of Brett from MacArthur Watergardens. The water was clear this year - I finally got the hang of it. In this picture, you can make out the outline of the steps - they are 4 feet deep. You can see to the bottom of the 8 foot section when you are upstairs in the house.
