Algae or Cyanobacteria? What to do?

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!

Keep cleaning your glass and siphon off what you can with airline tubing. In
about 2 weeks, the bloom is over. It looks like two different things to me... a
diatom bloom and a small section of cyano bacteria.

This is common in a newer tank, and while ugly, it isn't a permanent problem.

Marc, do you need to keep on siphoning this, or can you let it sit and
it'll disappear on its own?

What I do is put up with it until it drives me insane, which doesn't take much btw,
and then I grab a hose and siphon it out. And each time I've had to do this, it
didn't come back. I don't know if I just timed it right, or if it was near the end of
the cycle or if I just got every bit of it.... but I feel like all of this stuff is
just par for the course.

This is not an observational hobby, it is truly interactive. Although I have to say
this, I spend a lot more time online talking about reefs than enjoying my own!

Bob,

I use that method for flatworms, using a micron bag, but not cyano bacteria.
Whatever comes out goes down the drain.

I've got the same problem for the last 10 days or so.
I also siphon mine off by taking a rubber hose and
doubling up a nylon stocking as a filter on one end
and put that into my sump. It does come back and
maybe it's because some is getting though the nylon???

Siphon it out. It will probably come back. You need to address the
cause. Do you have lots of circulation in your tank? Dead spots? Is
your skimmer working optimally? If you are like me you are probably
overfeeding. Cut it back. I reduced mine in half. My fish did not
skip a beat. Your tank is new so it is probably not your bulbs although
this can be a cause. Too much nutrient in the water is the most likely
cause so look for ways to reduce it. Good luck

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).

Hello. My problem is getting worst! Bad part is it's spreading onto my rocks
and coral!!! What can I do? Is it going to kill my macroalgae (halimeda),
polyps, mushrooms, coralline?
I heard mexican hermit crabs will eat the cyano, but
I can't find any around here... I live in Southern California...
anybody know a place that sells them?

Thanks

where in socal its a big place

I live in Orange County... but if the mexican hermits will really get rid of
most of the cyano/diatom and whatever else i have, then i'm willing to drive
to san diego, LA, riverside, etc!

Or should I just get a powerhead and direct it right above the sand?
