cynobacteria...

It can be many colors but mine is always reddish and it is a thick mat that coats things. Looks like thick algae mat.

i think i might have it brown covering all my live rock and a lot of my live sand also. some parts on the rock are growing straight up with air bubbles on the tips!! how stange......just adde semi cured rock a week ago 25 lbs and live fiji sand 2weeks ago 60 lbs in a 55 gallon tank thought it was algea but i'm not so sure now

The culprit is most likely the flake food. Will try and find the chart again, but once saw a chart showing phosphate release from different types of food. Flake types were in all the top spots, I think it was Tetra Marine that took number 1.

along with the Chemclean maybe try a new food. All my fish love NLS pellets. And it wasn't even on the list.

There is a great article/letter in the latest issue of Aquarium Fish magazine in regards to cyanobacteria...

just read adding a macro algea will help?

 

[tangov559]

those are all good ideas...thanks

 

[bertoni]

Growing and harvest a macroalga can help. It did for me.

The problem with Chemi-Clean and similar approaches is that the cyanobacteria often returns. Mine did.

 

[tangov559]

i used chem clean last nite.....cyno is still there...how long does it take for it to go away?

 

[bertoni]

It might not be cyanobacteria, but another round might kill it if it is.

 

[tangov559]

well, today i did another round of chem clean...when am i suppose to change the water...how many days after it??

 

[bertoni]

I would start now.

 

[tangov559]

i did a water change after the first round already...again?

 

[bertoni]

Yes, I would, if the second round killed anything. Otherwise, the decaying organisms become food for more algae, etc. Chemi-Clean is an antibiotic, I think.
