So I'm entertaining the idea of doing a canopy for our 90 gallon that we'll be setting up soon. I currently have a 4 piece glass top for it. My options for a top right now are to use my tops that I have for my 55g and a add a piece of glass on each side to close it off, thus meaning I would be using two 18" T8 lights. Next option would be to use two LED strips I currently have on another tank + the 4 piece glass I already have. Last option (reason of post) is to build a canopy out of wood, that would have a flip open front and I could hand my fancy pants LED lighting system I recently bought used lol. That light is meant to be hung and is about 36"x10". (QUESTION I'm curious as to how far above the water line it would need to be to have the best coverage? I like this look of canopy I found via Pintrest: My DIY Stand and Hood The light I have looks like this: More than likely, I would paint it black, since the stand I have for he 90 gallon suffered some water damage from the previous owner, so I would want to paint it black as well... Thanks in advanced!
