Here's an update on the refugium project. As you can see, we've added some water lettuce, but the individual plants have also sort of spread out and are doing a good job of facing upward into the light (at first, they were kind of laying over sideways LOL). All in all, I think it's worked really well. I was afraid we'd kill the water lettuce before it could do any good -- apparently, a very easy plant to keep (especially when you have four huge fishes providing fertilizer).
