I live in the UK I have a blue orfe lve had it for 2 years now without any problems, ( we have emptied our pond of deep sludge, and refilled it with water) which l have added 2 sachets for pond problems we also done a strip water test which shows our tap water has hardness which was included in the 2 sachets l put in the pond. I have noticed the grey orfe has a patch on its back what looks like a green algae growing then over the weekend it disappeared showing that some of the scales missing underneath, l added some stuff for parasites then added it to the pond water over the weekend now today the green algae looking patch is growing again don't think the fish is eating now. What can l buy to stop this happening please can l have advice on this problem.
