I bought an aerotank that the seller says is authentic from ebay. Went to szkanger.com to verify its authenticity but I can't access the website thru my pc but I can with my phone. So I entered the code and it said 900 people already checked it. Shouldn't I have been the first? I'm confused. I still continued to use it on my vtr but today (which is the second day of use) I noticed a brown liquid coming out of the threads. The juice was all clear in the begining. Should I stop using it?
