Oh and no need to feed fish - they can live on all algae, watercress, gnat larvae etc. They won't starve, by actually feeding them food u encourage extra waste and add to your problem. I wasn't sure about not feeding fish but it works. Having started a pond a couple of years ago , it all looks after itself and I've not fed my fish - they are breeding and living healthy & happily.
