Child Tax Credits?

So from my understanding, the Child Tax Credit is worth $2,000, but only $1,400 is refundable. Ok. Then they throw in the Additional Child Tax Credit worth up to 15% of your taxable income of anything over $2,500. What is the difference between these two credits? Do you have to take the ACTC to even get the refundable portion of the CTC?

It's the same money.  First you apply the money to your tax bill.  If money is leftover, then the ACTC comes into play.
