I have an idea, and was wondering if anyone ever had done something similar, I have a 29 gallon aquarium, and equipment such as lighting, heating filtration to go along with it. I want to fill the aquarium half way and have the middle filled with LR and leave some out of the water, where I can grow a plant or too above water level on whatever surface I can make. If you have any suggestions or links to similar builds or ideas it would be great. Thanks.
