About Seachem Flourish Excel Bioavailable Carbon
Overall Feedback:
83% positive
89% praised for its ability to control algae growth
This product not only supplies the carbon needed for plants to thrive, but it also controls algae. I had a real problem in my tank with red brush algae and this product eliminated the problem and brought it under control.
After using 'flourish excel', the algae died off and we noticed that all the fish started eating it.
I used the product at a higher dose for two weeks with regular water changes and it helped in controlling the algae.
The product drives a wedge between aquatic plants and algae.
