After a month, and after adding high powered actinic and metal halide lamps to our tank (plus a 12-LED blue "moonlight system), we finally got the desired algae bloom. The snails, hermit crabs, featherdusters and various anemones are thriving, and we have a good population of small buggy critters, also highly desired. The snails are laying eggs, the Aptasia are thriving (perhaps to our regret, later) and we've even got some broad leafed algae that looks very nice. The tank has cycled twice (nitrogen) and everything is staying in bounds - ammonia, nitrates, nitrites. Now for some patience...
I clipped the tank out of this image, annotated and color balanced it, you can see it here.
Since many of the blue green algae are using chlorophyll A and B I
can give them the same light wavelengths that I would give to a
plant. Here you can see my 20W LED pizza pan setup being used to try
and help the algae grow. Normally I would just put the algae outside
and not waste the electroncs, but it has been dark and stormy today.
Some species of algae have evolved to grow in small pockets of meltwater found on/in bodies of snow. Seen here as specks and paint-like blobs of goop are flourishing colonies of the common alpine alga, Chlamydomonas nivalis.
For the record I stuck my finger in it and used the goop to finger paint on the adjacent rocks.

This is the San Francisco Bay just off Menlo Park - looking north. You can just pick out the Port of Redwood City on the right about 1/4 from the top
This is a run-off stream in the Black Sand geyser basin. Because of the different temperatures of the water, different algal, bacterial, and (in the hottest water) archaeal species live near the edge, vs. toward the middle of the stream.
This algae was so dense that I thought it was moss at first glance. Either way I thought that it was growing in an interesting formation and made for a good composition.

Brown algae, whose scientific name is Phaeophyta, has 28 species in the waters off of Guam.

Harvesting Algae in Srinagar. Was told that it is fed to cattle, but that it HAS to come out or will overwhelm the lake. I guess the polution is bad.
