Default DNA 2D Barcoding for Mitochondrial DNA

Hello everyone! My name is Kramer Kaplan, and I am a current graduate student working on fish genetics. My advisor and I are learning how to go through the process of 2D sequencing to obtain the entire mitochondrial genome of two species of freshwater stingrays. I wanted to submit a post here with several questions that I had. We have been using a PCR Barcoding Kit (EXP-PBC001) that has the twelve barcodes and barcode adapter mixes (BCA). I was wondering when you use that adapter mix because it does not say anything about that in the protocol. I'm following the "PCR barcoding amplicon sequencing for the MinION device using SQK-NSK007." As I have been following this protocol, the issue I have been seeing is my concentrations of DNA keep getting less and less until I have less than 20ng/ul. Before prepping the MinION, I am supposed to have around 150ng/ul of material. My first found PCR product showed about 10kB on a gel, and the concentrations were high enough, so I truly do not know what the issue is. If anyone could shed some light on these issues or offer any advice, that would be greatly appreciated!
