Review on API ALGAEFIX Control Solution 16 Ounce by Ryan Olsen

This product says "fast acting" on the bottle. Not fast enough for me. Depending on the size of your aquarium, you dose this product every three days until it kills the algae, and then dose once a week. It took three doses (9 days) to kill an average amount of algae that left a film in my tank. I then had to use an algae scraper to remove the film from the dead algae. If it worked faster I would give it a higher rating. This is a mediocre product at best and I wish I had bought something else.
