Hello, I am just starting to get into using tanks. I have tried the IClear 30 and the Protank. I am getting ready to place a order for some new juice from Ahlusions (never tried but heard good things). The site is asking me to choose my PG/VG mixture, I have never really done much research as to which works better in tanks or does it matter? Is it better to go 50/50, or higher lvl of one or the other. I would be grateful if someone more experienced could give me a crash course. Thanks a bunch
