Thank you for that answer, and taking the time to answer my question.

I want to make my base stronger. I have bought a 120/mg bottle of 50/50 mix at a 12mg nic level. I want to make it to a 24 mg nic level. My friend has given me a bottle of pure nic with 100mg in it. How much nic to add to it to make it 24 mg strenght. I cant seem to find my answer online. I have come up with adding 1440 mg to it. Will that make it 24mg strength? Or how much nic do i add to my 30ml bottle? I hope I got my question across right?
