Flourish Excel is an alternative to CO2 injection for planted tanks with fairly low lighting, its also useful in killing off certain types of algae.
its made by Seachem and most LFS sell it, alternatively you can get it off mose internet aquarium supply shops too
Does it kill off green algae
The past couple weeks Ive been getting green algea its hard spots that cover the glass.Does it kill off green algae
Could you be a little more vague, please.![]()
Excel is best against BBA and staghorn, which are both black and closely related to CO2 issues. It can help against other types, but may not kill it completely.

I don't think it'll help directly, as I get small amounts of this on rockwork and use flourish for my plants, but if you have a reasonable number of plants, it might help indirectly. Healthy plants tend to outcompete algae for nutrients, and a moderately or heavier planted tank will often get to a point where you don't notice algae growing.
