Great results Felix 🙂 how many doses were required to clear it up? Did you remove any manually?
I removed what i could manually by just pulling what i could grab with my hand.
On my first water change i applied the LC directly onto the affected area while it was out of the water and left it as long as i could while doing tank maintenance.
Next day it was pretty much all yellow. I have only applied it directly onto it twice but i have been dosing daily just not directly onto it!
So i'll say it has taken 2 directly applied doses while the affected area is not submerged!
