[Sk8r]

Report: after 3 days with no light in the main tank, 18 hrs light in the refugium, we're on actinic today. The main pests that I wanted to scotch, the bit of cyano and the caulerpa---well, the cyano is almost gone; film is non-existent; but the caulerpa grew. It did, however, grow tendrils rather than grapes, which may say its feeling the want of something. I sure hope so.
The battered acropora aculeus is still alive, but weak; the mille survived; the clam wasn't happy, but is looking much more cheerful now; and the lps and the aiptasia are ecstatic: that's frog, hammer, fox, brain. Gps is happy. Sand is white.

Interesting about the alk observation [and my sympathies] I run a kalk reactor, and tested during the lights-out, finding no problems, but I have a very light coral load, too.
