I have a Phiniac xl tank and I absolutely have fallen in love with it. My only problem is finding a good carto to pair with it. I want to punch my own and have been doing so with very limited success. I am punching exactly as Phiniac suggest using the punch that they sell in the tank kit they sell. I bought 4 packs of Boge cartos and I hate them and feel that it was a huge waste of money. I know that many people have been having problems with these cartos and I pretty much have the same problem. Bad taste, duds, flooding and most of the ones that do work don't even last a day. Is there any carto out there (punched or unpunched) that is made specifically for tanks the size of the xl? Thanks for any help guys, for now I'm going back to dripping.
