Would you say my Blade Grow 12" is defective after looking at the photo? The light seems to be more blue towards one end, and very noticeable on the sand bed. It's not the rocks or shading or anything else doing it because when I flip the blade around the other end of the tank ends up more blue. The individual LEDs in the clusters all seem to be lit, and not dead. Is this normal fluctuation, or a defect? Opinions, especially if you have one yourself to compare? To my eyes it looks bad. Thank you.
