Hi All
On Friday of last week Dean the manager of a local Fish outlet in the Plymouth area contacted me.
He was very worried about a cluster of Koi deaths in the area of St Budeaux Plymouth all the pond owners are non Section or BKKS but all ponds had higher than normall PH at 8.5 and all the fish had damage to the gills fins and were very slimey (from what I gather the problem started after water changes).
He stated he had been on to South West Water on a number of occasion's and each time the company stated that the Water only had to be safe for human consumption.
