What you describe sounds much more like Cyano Bacteria. It
will grow like a mat or sheet on your sand, and you can even
gently scoop it together and siphon it out.

If nothing else will get rid of it, ChemiClean by Boyd
Enterprises will kill it off.

I am losing the war against red hair algae in my tank. My nitrates are 0
and and my PH is steady between 8.0 and 8.2. The temperature of the tank is
between 80 and 82 degrees. I have (2) 250W metal halides that are on 8
hours a day and (2) 45 Watt actinic lights that are on 12 hours a day. ( I
don't have a phosphate test kit...could that be the problem?)

The red hair algae does not grown on the live rock much. Instead it grows
every day on the sand. I rake it each night until there sand is white
again, but the next day it grows right back. I have crown snails, astral
snails, some unidentied snail, emerald crabs, blue legged hermit crabs,
brown lagged hermit crabs, but nothing seems to eat it. Any ideas?
