Fish Tunnel

rosie100July 2, 2010

I want to make a fish tunnel for my Koi and Goldfish. Will a new chimney flue be toxic? I would rather not use rocks. Any other ideas? Thanks

What is the chimney flue made of?

I don't know what it's made of. I was hoping someone in the forum would know and had experience with it.

They use to be made of red clay, the same as flower pots. Which I think would be fine to put in with your fish. I know there are a few people that use a cut piece of very 12-18" wide drainage pipe made of PVC.
