I have a 24 in glo light that doesnt seem to be doing the trick. The tank spreads about 6 inches past the light on each left and right side. I have lots of hornwart that doesnt seem to be getting much light. I find myself 'stirring up' the hornwort to provide enough light for the plants. Any lighting fixtures that i can put inside my overhead fixture that will provide substantial lighting? I also have jave fern and amazon sword that seem to be doing fine. But they are in consistent lighting. I also find myself turning the light on around 6am and not turning it off until 10 or 11pm. Plz help if you can! Really want to get my Aquascape properly done.
