Well, some updates. Have one Maxspect Razor running overtop right now. The Sunbrite fixture, well, almost lit on fire. I was very fortunately looking closely at the tank when I noticed the wafting smoke and orange glow coming from the fixture. Could have been seriously bad.
Doing some rescaping in there, the right side has some dry rock added (duh). After I sell some of the base rock you see on the left pile I will be adding more good stuff.
