i have a 55 fowlr but wanting to upgrade lighting to keep corals was looking at the current nova extreme pro 1081 or current nova extreme t5ho. the first one has 324 watts and the second 432 watts. didnt know which one would be better or if the second would be over kill. the second one says that it has 24 hour lighting where as the first i cant find anything on it that says 24 hour lighting. any help would be great even other suggestions for lights in the same price range.
