The Halimeda just appeared out of nowhere about a month ago. The alkalinity is kept at 3.5-4.5 and the Calcium is about 400 PPM.
It was suggested that the Halimeda would compete with the Caulerpa and perhaps choke it out.

Reef A with the afternoon sun

This is a shot of the whole tank. Click on it to make it larger. This photo does not show it as it appeared in its full glory with natural sunlight.

Reef A

I was in too big a hurry when I took this shot. I was trying to get it while the sun was shining directly on the reef and neglected to notice that the flash was still on. The orange coral in the center is a Montipora capricornis.

Reef A with sunlight.

Left side of reef showing a newer acro in the center. It has become well-attached to the live rock.

Reef A in sun

The afternoon sun is shining directly on the reef. The newest corals are the Acro in the right foreground and the Pocillpora middle, far left. I have had the Hynophora for over a year.

Reef A

In the lower center is a white brittle star. To see it better click on the photo to make it larger. There are many of these brittle stars in both reefs. However, it is more common to see only a couple of arms protruding from holes in the reef.
They are desirable for a couple of reasons: they will feed on detritus and they produce many larvae which will mostly go to feed the filter feeders.

A mixed colony of zooanthids in Reef A. I apologize for the poor focus.

Newest coral.

The latest coral frag introduced to Reef A, Believed to be a Pocillopora sp. It is glued to the wall of the overflow tower. I was informed that it came from sexual reproduction in tank with a bare bottom.

The beginning of the reefs

The Coral-banded shrimps home is just lower right behind the Golden polyps.

Reef A

The Coral-banded shrimp has come out during the day having detected food in the water.

In the bottom left-hand corner is a encrusting gorgonian which is reaching out for new territory very quickly.

The capricornis is surrounded by star polyps which appear capable of stinging it. The Xenia creates a problem by shadowing when they get too big. It remains to be sen what will happen once it reaches the Pocillopora (to the left).

Reef A

The orange coral is a Montipora capricornis which continues to grow very well. Once it reaches about 125% of its current size it will be "fragged".

Reef A

This small feather duster shares a tiny piece of live rock with colonies of Capnella and Xenia.

Center of this photo is a Singularia moved to this area when it began to decay at its base attached lower in the reef.
