After a long hiatus I'm in the process of bringing my 180G back to life and in doing so I'm upping the game; thinking about sump filtration, diy "stone" background and some in water led lighting. I'm not talking about the commercially available light bars but individual leds strategically placed to highlight certain features of the underwater environment. Anybody have any experience or thoughts on this? Obviously I don't won't to electrocute the occupants of the tank or the house it sits in!!
