I agree Peter why some folks have to employ people to clean their ponds and consult for them is beyond me .I'm going to drag the old leaves out, that's going to be it for this years 'clean out'. My water is good and the fish alive.
This appears to be very much an American thing every UK fish keeper I know does their own cleaning of both pond and filters and most of us are self taught in health issues , "some more than others" [there is nothing like reading up on a subject before you even start in a hobby]...............
The only consultant that our club uses is a health official and he charges nothing for his services he is also BKKS trained and he is in our case just for back up and for the more novice members of our club
About the only time he comes out to see Val and I is if we need help over a matter weve never come across before like last years lightening strike or problems with the pump as he put the plumbing of our pond together.
