I have Coraline growing on my pumps and rocks. It is now growing on my front and side glass but not the rear glass. The back of my tank is painted blue with a coat of black sprayed on over the blue so no light could get through...... My question is since no light can get behind the coralline and its not a pours surface is that why I can grow Coraline everywhere but my back glass?
