I have a Blagdon 400 litre free standing pond housing four large goldfish (they started out small) but I'm obliged to do a major water change every week as the Nitrate levels rise very quickly. I've been advised to get a new filter - one that can handle at least twice the volume of water ie 1,000 litres. I also understand that some filter media can house microorganisms that can consume Nitrates. So, I need help with brand names. Can anyone suggest a filter brand/model that will do the job plus the name and type of filter media that I could add to or replace the medium/media that the filter comes with. I'll need a pump to drive the filter so any ideas about that would be gratefully received. Many thanks, Brian Montague
