Does anyone have any quick tips on getting rid of blue-green algae? It seems to have been introduced to my tank and is spreading over my moss and anubias. I've lowered by light period to 8 hours but is there anything I else I can do??
Thanks in advance!
I'm having trouble with it in my brackish tank. Seems no one really knows the cause or a surefire way to get rid of it.
I'm thinking mine started because of too much light. Both intensity and day length. Cut back on both and the cyanobacteria changed from brownish green to bluegreen.
It could be low nitrates as they are zero. I'd rather not increase it because the tank is home to shrimp.
I used Maracyn 2 with limited success. It clouded the water to where it looked like skim milk. After a large water change and 3 days of filtration the water is clear again.
The cyanobacteria, even under the filters' outflow, continues to grow.

I have had over 100ppm of nitrates and my shrimp never died. I realized I had overdosed EI about 1.5 months after i began.Unless you have some super high grade shrimp that are really sensitive to ANY nitrates, I think you will be fine...

Plenty of people know how to get rid of it. Maracyn 2 is minocycline. Maracyn (no 1 2 or 3) or API Erythromycin are from what I can determine by my extensive 2 minute research data, are the same thing in different packages. This is what you need to eradicate BGA. IF it's actually BGA.
On another forum there was an extensive thread about BGA and the relationship between NO3 and PO4. In the thread there was an article which I share here:
Sigh... Pick up some erythromycin, dose accordingly with your filter off. BGA is a bacteria, and an antibiotic is typically the best treatment. You'll eventually need to figure out your nitrate levels, but using the RIGHT antibiotic will kill the bacteria.
