Many thanks EagleC,

Blimey what an amateur I am. I didn't use the filter & pump much because it never cleared the water and always seemed murky. I have never cleaned out the filter (its a pressure filter) as didn't want to destroy the bacteria that had built up inside. Do you think I should clean it out? And do you think I should empty say half the pond water and top up with fresh? I shall check the ammonia levels with a kit I'll get tomorrow. If it is ammonia then it must stick around for months coz there's not been any fish in the pond for around 7-8 months if not longer.
As far as I can remember the guy sealed the glass pond though there was a small hole in the bottom which seems to have sealed itself.

Appreciate your reply
