HCA: Hermit Crab Association

I’ve read that people use PVC in their crabitats. I want to use PVC for a second level.

My question: what do you do to prepare or treat the PVC?

I was thinking about using a fine grit sandpaper to get the coating and dirt or whatever off before placing in the tank.

Just wash and use, PVC for water pipe is completely safe as is.

Thank you very much. I’m going to get building hopefully next week. If I can remember how to post pics i’ll Show the finished product.
