I have already changed lighting some. I had the lights on 12 to 14 hours a day. the last couple of days only had them for 10 hours. I need to pick up a timer for the bowl. I turn the light at 7AM. When I get home at 5Pm Im turning the lights off. I don't really get to enjoy it with the light on. My goal is to let the plants take the bowl over then I will add some shrimp.
