Hey Michael, I just picked up a 75 gallon and one or two of those lights would sure do the trick! To bad I'm tapped out so close after Christmas, plus I am moving soon as well. If you still have any of them left in a month or so I will definitely be grabbing at least one off you. Thanks again for the twin 24" lights.
