Glad it works Dove - it made a huge difference to our pond. You can see right to the fish poo covered bottom. I just hope our plants start growing soon to cover it up a little!
I stacked a lot of pebbles up on side of the pond this weekend so that wildlife can exit / enter the pond and there's a shallow enough area for birds to bathe. Hopefully we'll be able to get the timber ordered come pay day and that's the pond finished.
