Unfortunately you've had a bad experience with a LFS but the ones around are very well kept and I know the owners and they all have real passion for fish keeping. Your research says PVC isn't safe well my says it is and I've had personal experience with using that, especially with sensitive fish.
You honestly can't say PVC is bad considering you can go into our DIY forum and see how many times people use it in the aquarium and in the plumbing. You can even google aquairum decorations and a vast majority uses PVC. Therefore PVC is not harmful to fish. http://www.qualitymarine.com/News/Fe...nks?-(10/11/10
