I added it today along with the 3 I had left and the kanaplex.TexasGuppy said:You have 1 pack left? I'd put it in.. Isn't that second round optional anyway? I'd need to reread the instructions. Plus, you still have most of the initial medicine since the 25% WC didn't remove much.
Just reread: 4 doses is the first round of treatment. Again, most of the meds are already in the tank, and the kaneplex is an extra add-on. I'd just add the 1 packet you still have from the 10 pack.
