I've never had any non-glass tanks before. I have a hurricane on the way and I can't find a pyrex tank for it so I worry about the pmma tank it comes with. Is there a complete list for the popular vendors on which flavors are tank crackers? I did a search but only a couple flavors, some with out brands.
A basic rule of thumb from me would be Citrus and Cinnamon are things to avoid. Obviously not very accurate, but it's a good way to be cautious,
Also Banana flavors seemed to do it as well, if memory serves me right. Haven't used a plastic tank in like 5 years though.
Polycarbonate tanks are still around?
I don't have any info on a definitive list of tank crackers, but Vaper's Hobby Shop has both the Pyrex and stainless steel tanks for the Hurricane in stock.
EDIT: the Pyrex tank is out of stock, but they do still have the stainless tank sections.
