I have three nice kryptonite carto tanks that I haven't been using for the last couple of months. My favorite , swagger , would clog up in about two days and unicorn blood in only one. That drove me to the iclear 30s which works great and lasts weeks with either. I remembered a tank with white beard that's been sitting for about two months. I tried it and lo and behold still worked great. I ordered some caramel tobacco and vanilla tobacco from velvet cloud and loaded them in the other carto tanks. Well after two weeks they are still going strong. Really liking the caramel and being able to use my tanks.
