Yes...only check levels once a week but as of sunday everything was right on point. It's the only thing in the tank that looks odd. I did recently get some zoa's and put them on the rack also and they are doing amazingly well, so I wasn't sure if this digi just needs lower light. I'll probably move it back down again, when I had it down it was fine, just wondering if there is such a thing as too much light for corals.
