The 6 gal version seems to have more ideal dimensions for a planted tank. It’s unique, contemporary design will surely make a beautiful showpiece in any room of your house.

The Edge is a great glass aquarium kit that comes with beautiful LED lighting and a filtration system that you can customize to suit your needs.

Not Exactly Aquascape Friendly:

Believe me, if you have to aquascape this aquarium and prune your plants, be prepared for a long day. The access hole makes it very difficult to maneuver your hand inside. Also, be sure to drain at least half of the tank water as well if you plan on trimming plants.

However, I would only recommend low to medium-light plants. The addition of Co2 is tricky due to the unique design and I would recommend against it. If done right, this can be a beautiful planted tank while remaining “low tech.”

Maintaining the glass clear and free of algae can be tricky. Be sure to buy a small magnet cleaner and decorate your tank so the magnet has room to move freely while on the inside. Drain some water before maintenance to avoid any overflow issues resulting from putting your magnet cleaner or hand inside the tank.
