Hi Folks,
Just thought I'd provide an update on Blue Exit. It did appear to kill off some of the BGA. But, you guessed it, now it's back. And it has spread to the water surface, attaching itself to an oily film that had developed there. I have just started another course of treatment. Now, here's a question for the experts - what species of BGA (cyanobacteria) are present in freshwater aquaria? I've come across the following but cannot find a definite resource that names these bacteria. Here are a few:
Microcystis aeruginosa
Oscillatoria Sp.
Anabaena circinalis
I've also contacted the makers of Blue Exit (Easy-Life) in the hope that I can find out which cyanobacteria are targeted by this product.
