One more update. To combat the film algae that grows rampantly on the glass, I turned the H80 up to 18 hours a day a few days ago. It seems to be working, as it now takes 2 days to get enough build up on the glass to bother scraping. Before, one day and I couldn't see into the tank very well, let it go two days and it was practically like paint. I know I have an abundance of nutrients, but I haven't tested to see exactly how abundant. Algae growth is still non existent in the display, other than film on the glass. Either the fuge or the CUC take care of anything on the rocks before it's visible, and that means both are doing their jobs. I do have a little bit of cyano growing on the sand. Dead center down front, and directly under the gyre. I'm positive this is a flow issue as it's concentrated in the two spots of the tank with the least amount of flow. They are little detritus pockets. I'll siphon them up when I do my water change.
