Well it's not actually a new pond, but after two weeks in a bucket of increasingly green sludge the goldfish are back in their home. Look how crystal clear that water is! You can see right to the bottom. As you can see I've added a new plant - dwarf papyrus. I had a little colocasia in there but the big floppy leaves blew over all the time. Hopefully these thin little reeds will stay upright. The water lily is also putting out new leaves and there's at least one bud forming.
The best part is, my patch job fixed the leaks! Hopefully I won't have to drain their pond again for a year, as long as I can keep the water pretty clean.
