The Coral Glow model features a LED mix that maximizes spectral peaks in the lower range of blue and upper range of UV that showcase coral fluorescence. It’s ideal as a supplemental source of “pop” that can be combined with a Blade Grow or used to augment your current lighting setup to make your aquarium truly glow. Peak performance is best achieved in a ratio of 1:2 Glow to Grow, but one of each is perfectly acceptable when less light is needed.
