Has anyone here ever attempted a planted BiOrb? I think it would be possible and I have some plans to get around the problems, just wanted to hear your thoughts.
What size BiOrb are you thinking about? If it's an 8 gallon, it might work. There's not a lot of room at the bottom, and you will need to be able to move the plants to access the filter. Another problem with the BiOrb (in my opinion) is the fact that the light runs off of the transformer that also runs the pump. There's no way to hook it into a timer, so you have to remember to turn the light on and off to regulate the light cycle.
Good luck if you decide to give it a try !
