Here are a few updated shots of the tank. The snails, reduced lighting and reduced nitrates have eaten away at the algae that was in the tank. The pics don't show very well how much better the tank looks but you get the idea.
There are a few patches remaining in the tank but I'm confident that the snails and continued reduced nitrates will have that mess gone in a week or so.
BTW...this is only 28 of the 42 LEDs running, Whites at 60% and Blues at 70%...Imagine how bright it is when I have them at normal intensity. (W-85% B-100%)
