Cyanobacteria!

[seamonkee]

Ok folks, confirmed I got cyanobacteria in my tank.. those mysterious black gooey sticky circles I see on my DSB... now spreads....

Any suggestions how to cure it? My water parameters are ok....

Salinity - 1.023

Ammonia - 0

Nitrite - 0

Nitrate - 5

How??? I know I got a long battle ahead.... besides, cutting down on feeding and working up on my skimmer? ANyThing else I can do? Help!

Also, I got siphon out a few....

Well, you got the idea down right.

Maybe also can try to reduce your bioload, buy polyfilters or rowaphos to take out the excess nutrients.

And lots of patience.

BLACKOUT?

i remember tanzy says using black trash bag to cover tank to starve it from light

Black? I thought it should be purplish in colour...

run lotsa rowaphos and phosguard in a HOB filter. i thought mine wont go away forever but it went after 1month+

patience..

It's a water quality issue.

Too much dissolved organics, phosphates etc.

Get rid of these and your cyano will go away.

Either do regular water changes, reduce overfeeding/overstocking, or usage of enough GAC and phosphate removers. Or upgrade your skimmer.

You are not alone, i also have an outbreak.

I do the regular water changes, big skimmer, carbon etc, but the one thing i do not use at this time is a phosphate removing product.

This may be a good place to start.

Arghh... me just saw 3 patch on my sand bed.. darn...

I use my cleaner to shuffle the sand, add poly filter and change my Seachem phosguard.. hope to kiss it bye bye..

[Golden Tooth]

Wat do u mean by shuffle the sand?

[aqua_reef]

Wat do u mean by shuffle the sand?

eh.. think shuffle isnt the correct word.. i should say i use the cleaner to "lawn" the surface of the sand where the cyano is...

hope they will be gone..~

I bought a huge snail (definitely not astrea but shell is pyramid in shape) and it was feeding on the cyano + diatom... Is it so that they feed on cyano as well? Because that's what happened and I dun believe what I am seeing...

[Dazza]

digicam spoilt leh now at Olympus service centre... never mind, I try to get a shot and post it up using my friend's camera... hehe...

[Achilles Tang]

Actually, nothing feeds on cyano. It's distasteful.

I've never tried it myself... so I won't know.. but all the fishes and livestock that I have ever kept these years would give it a wide berth.

I'm back today and the cyano has spread and cover the whole sandbed! Scary the way they multiply... at this rate, even if the snail is really eating the cyano... it will probably be eating it slower than it multiply....

Never mind, on the positive side, if I "survive" this ordeal, it would make me a better leaner meaner reefer... Damn u, Cyano!

[aqua_reef]

Argh... i just knock off from home.. came back and there they are again...

basket face damm thick.. i remove them and they come back again...

look likes i have to look for help..
