Pond oxygenating weed (IP2)

I have some surplus oxygenating weed available. Will be supplied unweighted in bags. They are from a chemical free pond, even water treatment if top ups needed is done with vitamin c. I cannot guarantee there are no fry, snail eggs or whatever else that may have got down n dirty in the pond however. So please if you have a fish free wildlife pond/garden and wish to keep it that way this may not be suitable for you.
