Hi All :;hi1 Hoping for some input on the last piece of hardware for the 40 breeder. Right now I'm looking at going with a Marineland LED fixture, just debating between single and double bright. Unless there's a suggestion for a different fixture, which I'm open to in the same or less price range. I don't plan on live planting, if anything a few low light plants. So, especially with it being a breeder that's only 17 inches deep would the single bright be enough? The double bright is, well, twice as bright at 1200 lumens as opposed to 600 on the single bright. The double bright is obviously a little more expensive and uses a touch more than twice the wattage, though the LED's are rated at a longer life span. Thoughts or suggestions? Right now I'm leaning towards the single bright unless there's a lot to be gained going with the double.
