Concrete?

What concrete is good for freshwater tanks? Quickrete seems to have many kinds, which one is okay?

Hey, if you contact Andrew McFadden, i'm sure he will gladly help you. You will be in good hands with Andrew, he has built some stunning 3D backgrounds in his freshwater tank, using Quickrete. He even has a thread on how to do it. Definitely worth a read.... Ian
