Truth. That's what is on mine and I have it at 60% AND suspended about 8" above the water line. The guys at Aquarium Co-op told me it would be too strong but if someone tells me not to do something it makes me twice as likely to do it. Well, they were right.I have this light on a Mr. Aqua 12 gallon long and I can tell you you most certainly need to either suspend it, or dial the intensity way down. The light is too powerful for such a shallow tank. You WILL get algae blooms.
Anyways, I'm thinking of getting a 22 long next which I think this light would work well with!
