Well, thanks to all that replied. If what you say is correct ( and you have been doing this longer then I have ) I will save a fortune on my water changes. I must admit I am a little dubious still so I will try what you say and only treat the new water but keep a closer eye on my fish than normal. Worse case scenario is that they start flicking and I up the dosage of dechlorinator but it will probably all been fine and I will have spent the last year throwing money in the pond.
Thanks again.
