stylish and modern ways to aerate a tank?
I have a 47cm cube tank with an aquaclear 70 hang on back filter, and wanted to add more oxygen to the tank, even though I have a hang on back, as the tank is slightly deep and I'm worried about not enough oxygen in water.
I do have an airpump packed away, although the clear tubing looks very ugly in tank. I even tried to buy suction caps for tubing, but they don't stick well and the tube is all over the tank, which looks ugly. Is there a way to make this look stylish and not ugly?
Or is there another way to add oxygen apart from standard airpump and tubing?
