Few pics of my DIY setup. First is top down view. Second is reflector i made by sticking some of the diamond reflector material to an old takeaway container. Inside the tank chamber is a spaghetti container with a hole at the bottom for the maxijet 1200 poking out of it blowing up the screen. Lighting has been on at 1500 and off at 0700. I'm now trying on at 0700 for 2 hours. On at 1100 for 2 hours then on at 1700 until 0700 to see what effect that might have. Sorry pics are not great!
