Here are some pics of placement in my tank. I have both my LPS
placed at the end of the flow cycle. I have metal halide lights and the bubble and frogspawn are approx 13-15in away from the light. I hope yours pulls threw with the rips in it. Moving it upside down was one of the first things the lady at the fish store told me and I'm glad she did. I go to her a lot when I have questions.
