So I wasn't aware of the cracking clearos... bought two wickless clearos worked great with strawnana and bangberry mist... but then I put in fire & ice... and the clearo fogged up and cracked from the bottom upwards.. so i put on another clearo and it gurggled...I was sooo disappointed.. I called the company I got em from since the clearlo's was only five days new.. and they explained to me flavors like cinnamon and spicy stuff and limes and oranges will crack the clearos... I did not know this... I understood I would not get a replacement on the one cause technically I broke it... so the guy I talked to suggested I get a pro glass tank... he gave me a $4 store credit so including shipping total came to $13 for the pro tank so not bad.. but ive never used a pro tank... so I'm a little confusled on how to use it., I wish I wasn't such a NOOB to this stuff... any help on how to use it & how they differ...would be greatly appreciated..
