A lot of upfront planning goes into designing a your perfect planted aquarium or aquascape. Hardscape, plant selection, lighting and CO2 systems are just some of the obvious considerations. But before anything else, the selection of the aquarium itself is what should be the first item on the list.
Larger capacity tanks are more stable and can accommodate more plants and livestock. Of course, smaller tanks can work very well with lighter bio-loads.
Consideration should also be given to the room and placement of your tank. An esthetically pleasing design will balance the dimensions of your aquarium with the rest of the room and its contents. Often this is a personal preference.
Long squat and wide are ideal dimensions for planted tanks. They have plenty of bottom space and importantly larger water surfaces for better oxygen exchange.
