Cyanobacteria

[silverwater]

Ive had a cyanobacteria problem for a few months and blackouts work for like a week and then it develops again. How can i fix this?

Have you tried treating with erythromycin? Worked very well for me in conjunction with a blackout. I also added a powerhead to my tank to eliminate any possible dead spots/flow issues.

+1 on the erythromycin

You may also be able to spot treat with hydrogen peroxide. Takes a bit of time but good if you just have a few patches.

Chemiclean worked wonders for me.

Erythromycin will get rid of it and it will probably not come back. I tried everything else before I gave up and did the Erythro. One treatment course, 5 days, and it was done. It will not hurt your beneficial bacteria at all. The Erythro treats gram negative bacteria and BB is gram positive. Just be sure to clean up the dead cyno or it will cause an ammonia spike.

This is what I don't get. Erythromycin is for gram positive bacteria in most links I can find (see below, although you have to scroll a bit ).

But I've seen a few threads now using this and ammonia hasn't lifted. Has anyone had troubles with ammonia and using erythromycin??

I believe nitrifying bacteria are meant to be gram positive however have seen one article that said they are actually gram negative but behave as gram positive - whatever that means.

I used peroxide so I wouldn't be bombing the system. Now I'm starting to wonder if erythromycin would have been fine.

Nitrifying bacteria are gram negative, although a ammonia spike does sometimes occur due to the mass die-off of cyano.

What's your tank cleaning routine?

I had it recur in a 3 gallon betta tank over and over. I even bleached the tank and started fresh a few times. It finally stopped coming back when I added live plants.

Many thanks for the info.
