reef165 Posted November 2, 2010 Share Posted November 2, 2010 yep, Cyanobacteria, to help understand why ya got it we need to know all water paramiters, what type of water you use for mixing and topoff, what you use for flow in tank, what kind of lighting and how old.

ReeFit Posted November 2, 2010 Share Posted November 2, 2010 most likely a combo of to much light and a few to many po4's hanging around. Quote Link to comment Share on other sites More sharing options...

Beckie Posted November 3, 2010 Share Posted November 3, 2010 I thought Cyano was red, kinda air bubbles in it? No green that looks hairy,string. Not affected by lights. Beckie Quote Link to comment Share on other sites More sharing options...
impur Posted November 3, 2010 Share Posted November 3, 2010 I thought Cyano was red, kinda air bubbles in it? No green that looks hairy,string. Not affected by lights. Beckie There are red types, orange types, black types, green types, pink types, blue types, brown types........Cyanobacteria feeds on nutrients, IE NO3/PO4, as well as thru photosynthesis.

grassi Posted November 3, 2010 Share Posted November 3, 2010 I think is cyano too. The only way to be sure is to look at it at the microscope. Bring me a sample and we will know Quote Link to comment Share on other sites More sharing options...
