The electricity is a amajor factor. I am running 4T-5, 2-VHO setup and had two quiet ones (sump return, closed loop)My electricity keeps tripping and while I was away the sump return pump tripped and I came home to a bunch of dead fish. If I downgrade the lighting and plug the closed loop I am hoping not to have any circuit problems and my fishies can stay alive. Besides, everytime I go to the LFS I drool over the triggers...
