I have a new pond. Can I use a giant clamshell (real) for a waterfall feature in the corner? It is about 500ga

Question

I want to know if a real clamshell will hurt the fish. I have a great filter (fish mate 3000with UV). The shell is 36 inches across.

Answer 1

I think you can buy a spray silicon to cover it. The calcium break down might be too much for koi- if that's the fish you are going to use. Don't forget water birds will snack on your fish in the wee hours of the morning.

Answer 2

yes you can use the shell but you should be awear it will probley raise your ph level over time

Answer 3

that will look great but I would try to coat the shell with something so that it doesnt deteriorate over time...be sure to use a product that is fish safe

Answer 4

As long as the shell has been clean thoroughly and not carrying any bacteria on it you should be fine.
