I just started using new cartos I got last week and so far the first 3 gurgle like crazy and drip juice through the battery end! I've been using my sub tank and M&P cartos for a while now and never had this happen. Nothings changed - same tank, same juice, same filling methods, etc. I'm looking at the holes and they seem to be bigger than previous cartos I got from M&P. Any ideas on what to do? I threw out the first 2 thinking they were shot but now I'm thinking that's not the case..... Help, I'm almost out of cartos (and money)!
