I've tried searching but the info on here is years old. Just bought a nice pair of Blue Turqs and starting again since the 70s. Just starting with a single breeding pair in a 2ft x 2ft tank to keep things simple to start with. I do have a light unit that fits the tank but it stopped working years ago. Now I'm thinking do I upgrade or buy a new one? I'm told I can buy leds in the shape of T5 tubes but I'm completely in the dark as per modern lighting. Any help will be much appreciated. Thanks.
