Hi guys, So recently I bought an AL85 with the included tank (the baby beast) and my friend bought an Alien 220W (also with the baby beast) and we noticed that his tank is a little big bigger. I think my tank just fits about 2 ml and his tank would easily get to 3ml or even more. I googled if there are different baby beast tanks but I couldn't find anything. Can you guys help me? Thanks in advance!
