Center background is a newer Flame Scallop. The one that had been around for a couple of years recently succumbed. On the right is a frag of the Star Polyps. On the left a frag of the Montipora digitata.
Reef A

In the center is a M. capricornis. It has darkened and grown since the salienty was adjusted.
This is Reef B. The leather corals that were doing well in this system began to decline due to the hypersalienty

Reef A:

The mother colony of Pocillopora is behind the base of the gorgonian. It is also recovering nicely from the hypersaline condition.

Some of the Xenia were recently fragged. The Trumpet coral in the rear does not appear to be recovering however.

Note the Pocillopora in the middle of the photo.
A couple of weeks ago I was checking my sp. grav. against a new hydrometer. It showed the water at nearly 1.040 with the new one when the old on read 1.025. My conclusion: old hydrometers need to be replaced every couple of years. In the meantime rinse them in fresh water and occasionally soak them in white vinegar.

Before this I could not explain the bleaching of this and loss of some other corals. All other parameters were WNL.
Zoes that had been added to Reef A but refused to open until the salienty was corrected.
