Thanks! I'm realizing that it's a whole lot less light (don't tell the led advocates I said that). After two weeks I'd kill for my halides back, but the tank needed to be way more simple than it was (smaller, no sump, no chiller). Now the clam is about half as deep and right under the led that's running at half power. The first week I ran it at 25% power.

Ironically, I'm also wondering if I'm actually hitting the clam with a whole lot (too much?) Of certain wavelengths.

Clam is less responsive to shadows and seems open pretty wide, but is still retracting at night. The tank also has lower dissolved nutrients, so that's also a concern. Ugh. I hate making big changes to the tank so fast. It had to happen as a part of a recent move.
