I installed the steel wall panel with the light niche upside down so the light niche is too high. According to specs it needs to be 18 inches below the surface of the water. Seems impossible to fix at this point. Should I just put a cover on it and make it impossible to install a light cord or is there any type of light that doesn't have a mounting spec of 18 inches water? I wonder why the 18 inches deep?
Thanks for any suggestions
