Using a roller didn't give a smooth texture and sometimes bubbled, but that may have been the roller I was using. The best effect came from using an airbrush gun, if you have access to a compressor. Even without much skill or practice, you can get some neat looking texture.

This quote really caught my eye, and no one else commented on it... I've painted FW tanks to avoid a peeling background, but now that I'm doing a larger/reef tank I might try the background.
