I have hornwort in all four of my tanks. Two have no algae what so ever. The other two have some to a varing degree. In one of those, the algae is very minimal and not really a problem. However, my newest tank has been battling a mild case of green water almost from day one. This tank also has some very bright green algae that has grown on some parts of my driftwood. I don't mind that, it looks rather nice.
I have no doubts that hornwort can have a positive effect, but as you can see, its not a cure all.
