Hello Reino, don't get despondent about your pond, there's lots of help about. Some of the places that sell the water plants will advise you on what you need. With regard to the 'bucket', you tip the creatures gently back into the pond,ie, when you are pretty sure they've come out of the weed, you take the weed out of the bucket, leaving the creatures in the bucket, then lower the bucket into the pond, tilt it on it's side and gently tip them out into the pond.I'm sure someone will come in and leave you a link for a good informative web-site on how to 'do' ponds. Actually, I could do with some help myself, although my pond is well established, I'm sure there's some management I'm not doing, for fear of doing the wrong thing...At the moment I'm at the ''If in doubt, do nothing'' stage.Good Luck with your pond..Posie.
