I know the answer to this is in here somewhere but I just could not find it. I just made a syringe tank on a 2.0 boge carto and filled up the tank. I have read somewhere that if you look in the top, the filler will still apear white so how do you know when it is ready to go? I have also read that you should not fill it manually from the top like you would without the tank. That particular advise is very hard to follow. I am looking at that white white filler and I really want to drip on it. It looks so unhappy!
