This only supports what i said previously about risks. Any product that will outright kill algae is likely to have detrimental side effects on fish, bacteria, lants, or whatever.
Hey, it's in general plant topics.
I read a scientific paper recommended by Tom about the algaecidal properties of Excel and the effects as well on shrimp. I've been using 5ml daily in a 25 gal tank with shrimp, snails without bad effects as far as I can tell. Not much algae and plants doing well.
