You're going to have to spot treat it. I wouldn't just dump it in, I don't see that working out too well.
I've been using 1mL per 1g when I spot treat my tank.
Now, spot treating will only help with getting rid of some. What you really want to do is find the root cause (fluctuating CO2 values) and correct the issue.
Can you tell us a little bit more about your setup (lights, co2, how long lights are on, fert schedule, light and co2 timer schedule)
