Clearfast Overdose!

[Momma2fourboys]

My helpful 3 year old dumped aprox 60ml of nutrafin clearfast in my 45 gal tank. I have done a 50% water change, is there anything else I can do?

What's the recommended dose on that?
 
You could also try; another water change, if at possible; watch for any odd behaviour, increase aeration (lower the water level, or raise the filter slightly, if needs be), add carbon to the filter (but only if you can do that without removing more than a quarter of the other media)
