I have been doing tons of research on starting a freshwater, heavily planted tank. At first I was considering a tank with the enclosed filter, heater, etc., but these tanks seem to restrict space for maintenance. Then I came upon a Clarity Plus 36g bowfront acrylic tank with an internal corner overflow. Does anyone know if you can put ceramic bio balls in this overflow. I like the fact that the overflow will keep the water off of my wood floor in case of a power outage. I am trying to develop an uncluttered, balanced tank. I also want to use led lighting for cost and to limit water evaporation, but the tanks I have been looking at don't give any specs on how I would attach the lights. Do they hand above the clear tank cover and shoot through? Very confused.
