Koi-Pond-Pain 

Well more rain and still cold pond temp just 9c stayed at the pond last night was in so much pain I could not sleep and after all the pain killers still pain so sat out in the dark in the cold such a lot to catch up with on the pond .
I wonder if those who have had a lot of fluke and costia have tested the drinking water although water is treated Im sure some bugs could get through and possible get into the pond.
