blue-green algae

Re: blue-green algae

I had a nasty case of BGA that Tom just helped me get over, in my case it was a low nitrate situation. My test had been reading 5-10 ppm, but I didn't really believe it. Mine was a pretty severe case though. I don't know what would cause the minor occurance of BGA.

 

Re: blue-green algae

You must have gotten a hold of some of my water! Erythromycin, at half dose, I believe, is a good treatment for BGA, worked well until it was reintroduced. That's the main "cause" of BGA. It seems to like nutrient-rich water but also areas of low water movement, IME.

I think that if one looks closely, he will find BGA (and many other harmful bugs) in most planted aquariums, tiny populations not doing any harm but just waiting for the right conditions to go forth and multiply.

The right conditions could be anything that significantly changes the status quo in the aquarium, like an increase or decrease in nutrient levels, lighting, or temperature.
