I made my (second) pond around 6 years ago. Initially, I was happy with how it looked.
Like most things, the imperfections started to stand out more and more.
Besides the fact that the water is getting foggier as more time passes, I really don't care for the dark pond bottom and sides.
Cutting apart the 'water' was a pain.
I found it much easier to cut apart after soaking in boiling water.
I even found a frog that I forgot he was in there. Couldn't see him before.
Some broken tails (and a decapitated turtle), but they all can be salvaged. They are not as vibrant as they once were. I will have to find another deli tray for a pond before I can start again.
