After I suddenly in the aquarium got problems with filamentous algae and black algae and this did not get with conventional remedial proposals in hand, I came here on the algae-Ex. Because of the reviews I was a bit skeptical, but the agent has even eliminated the black algae without the vegetation or the fish suffered.
Every now and then diving to new algae, which can be due to algae-Ex eliminated then within a short time and with low doses but.
