can you use too much inhibitor?

Hi, I had to drain some water from my combi worcester 28 system yesterday. I'm guessing around 20 or 30 litres but I'm not sure.
Having very recently learned about inhibitor I'm guessing I need to replace some.
It comes in a tube that treats 100 litres.
My question is because I don't really know how much I took out or how much my system holds what would happen if I stuck half a tube in "just to make sure".
Can too much inhibitor damage the system?
Any advice on replacing the inhibitor would be most welcome.
Many thanks,
Rob.

It normally says in the dosage instructions that there is no problem from overdosing. Better to be a bit over than under.
