I did a little tank maintenance last night, such as cleaning the circulation pumps and pulling out some of the hair algae (bryopsis) so here are some new (and hopefully improved) photos.  I also started dosing amino acids for the corals today, in lieu of feeding them as regularly.  The idea is that the amount of nutrients in the water will decrease while the health, color, etc. of the corals will improve.  This concept is the brainchild of Chris at Einstein Aquatics.  There should be noticeable changes in coral colors in a couple of months, so it will be interesting to look back at these photos then.

The tuxedo urchin has started camouflaging itself with random objects from the bottom of the aquarium:
