ok i know a way that would work for you but runing the ac unit at a remote location
take some 6" flexible ducting and duct tape it to the ac unit output and run it to your tank canopy with screen over the opening to prevent fish or other things from getting in
this would probly be a lot safer and less anoying looking than using the ac unit actualy on the tank canopy just rember any air that is pumped in has to get back out |
