That's actually normal for my RBTA even when it was under the DE. They tend to bubble up at night but during the day, they reach for the light.
Here is a pic with DE MH only. MH-only produces very washed out pictures. Actinics add too much blue.
Here's what I like better about the first pic. The first pic seems to have better contrast. This is easy to see on the Frogspawn (you can see the brown) and Yellow Leather in the first pic. The green Zoos are green. The blue stays blue (Tang and clams stay blue). The red stays red. The coraline on the rocks and glass show up so much better too. The water is clearer instead of blue or white.
In the MH w/ actinic pic, the red gorgonian looks blue. In the new pic, the red gorg is behind the rocks so its not visible. But if it was in the front, you'd see a red gorg that is RED.
