I have a nano tank (23 gallon aquabox). I'm brand spanking new to this hobby and am very excited. My tank is just at the beginning stages of cycling( Clown fish pair). The Tunze 3155 is not available and am wonder if I should get the nano version or wait for the 3155 to become available again. I get, at this point that the 3155 may be a bit much for my tank, But is has amazing reviews and I know I can set it to the nano setting. I want to do right by this tank and it's future inhabitants.
