I've had my 46 gal bowfront for 1.5 years now, and I've NEVER gotten rid
of the problem. Its been worse at times than others, but its never
totally gone away. It used to be rampant, now its just mild and annoying.

I used to have green hair really bad too, but that totally went away
(hurray!). Cant solve the cyano problem tho. I feed only once a day,
have a good protein skimmer (AquaC), lights only 10hrs/day, water
change/siphon every 2 weeks (more when its bad). Oh well, I'm going to
the gym regularly, so soon I'll be strong enough to chuck the whole thing
right out my 6th story window :-)

Oddly, I have a small 7 gal nano reef that does have high nitrates
(30ppm) and I've NEVER had any cyano or green hair anywhere in that tank
(about 1 yr old).

Hi, I have a 1 1/2 month old 60gal tank w/ about 30-35 lbs of live
rock and 60 lbs of aragonite sand. A few weeks ago, I've had a bad
problem with this purple/reddish fast growing stuff on my sand and
glass! It is now beginning to slowly appear on some rocks. I sifted
the sand manually and some of it has now turned brown... Areas covered
from the light by rocks, etc are still white sand. It looks sorta
slimy and hairy. What is this stuff? How can I get rid of it?

Thanks!
