Scottish Water has issued a warning to fishkeepers about using tapwater in ponds and aquariums during the current hot weather.
The authority says that a number of fishkeepers have lost valuable collections of fishes after failing to correctly dechlorinate their tapwater before using it. Some fishkeepers use small amounts of tapwater without treating it (something PFK does not advise) with no ill effect. However, as chlorine levels are higher than usual at the moment, using untreated water is causing problems for fishkeepers.
PFK advises that all fishkeepers use a good quality dechlorinator at all times. Preferably one which is also capable of neutralising chloramine and ammonia: many common dechlorinators are incapable of removing chloramine adequately and this chemical is much more toxic to fish.
