Ok, thanks Hoppy! I had asked a question on the San Antonio Aquatic Plant club Facebook page, regarding how much extra light I need to plan for if I want to suspend an LED fixture over my 20L instead of having it rest on the tank. Some have said that the fixture may produce too much light for such a shallow tank, so I may raise it up a few inches, and thought I would see if there is any formula for how much the light diminishes per inch raised. If you know of any article on that topic, please send me a link; but otherwise, thanks and have a great week! Neat drawer slide apparatus, by the way.
Hi Hoppy; someone recommended that I read your post about suspending lighting over a planted tank, but I can't seem to find your previous post on that topic. Any chance you can give me a link? I'm trying to study up for my first planted tank (just a 20L). Thanks so much!
