I have had either dead slugs (hurrah) or rotting bits of tree go down the
pipe into the waterbutt. I just emptied it and have cut back the tree and am
going to put a filter on the pipe and seal it better but wasn't sure what to
clean it with that wouldn't require hours and hours of rinsing. I have
already scrubbed it but it smells a bit still. Is smelling water ok for
plants (not seedlings)?
