Using Algaefix in a tank is risky. Although there's people who've used it with no problems, there are also those who have lost fish because of it, including myself.
I admit Algaefix is pretty darn good at getting rid of algae. But if there's a problem with your tank setup which is causing the algae, then chances are it will only be a temporary solution. As long as the problem exists, the algae will keep returning, meaning more Algaefix and more risk.
It's better to try and solve the problem. Post details of your algae and tank setup and maybe we can figure out what's wrong.
