I got a DCT carto tank from Liberty Flights. They are made from a plastic that won't crack...poly...ummm...not polycarbonate, they other one.What are you using if you don't mind my asking. Figured you may save one of mine because I have several juices that I've not put a drop into the vision.
Also, what other tank system did you get?
Here is what I used:
Cola
Pina Colada
Peach
Pineapple
Pear
Key Lime
Watermelon
Sweet tart
Spearmint
Ripe banana/marshmellow/cupcake some with some almond
Mint chocolate chip
It's the ripe banana that did it. Probably on all of them. I mixed my own.
Check out the list here:
