For years I have fought in our two aquariums with thread and brush algae. Especially with the manual removal of filamentous algae I came barely behind and with all the troubles and the unsightly, went a quite a bit of the fun of it. All the advice that we received regarding lighting, fertilization, water values and feeding amounts, did not lead to success. By chance I came across this medium. Besides fishing I also shrimp, which are very sensitive, but the agent should be safe for them. I was skeptical in any case, that would be nice if the so simple would ... After two weeks and two applications (somewhat lower doses than indicated) was to notice a significant improvement. After six weeks, both tanks were nearly free of algae. In a still a few brush algae, but that's ok now I give only every four weeks a small amount into the water. The plants look tip, fish and shrimp have not responded, and are wide awake and I make the aquarium again joy.
