Hello. I am helping my sister plan out her first reef tank. This is supposed to be a relatively inexpensive tank just for her to get her feet wet and try the hobby out for herself. She has decided on a 24" L 6.6 gallon aquarium (9" deep) and we are now considering what would be appropriate lighting for this tank. On the Marine Depot website, the Marineland Double Bright fixture is compared in a video to the Marineland Reef Capable LED. But the exact Kelvin temperature of the Double Brigth fixture is not given (aside from just "whites" and "blues"). Could you please address this and give us a bit of info on it? Your help is much appreciated. Thanks in advance.
