Anyone use T5 lighting for plant growth and colour enhancement in fish? I know it's popular for marine but was wondering if it could prove useful in freshwater. Any comments?
T5 is the diameter of the tube itself: T5 is 5/8", T8 is 8/8" (i.e. 1", standard slim tube), T12 is 12/8" (1 1/4" normal household tube).
