I made an horchata mixture of 5% using the plain tfa horchata. Had it in my plastic tank for about a week. Notified it tastes like a heavy cinnamon flavor but can't find information on it. The tank did crack, but the tank did survive a previous issue in which it was scratched. Does a tank crack over the period of a week or is I generally instantaneous? Has anyone else had a problem with cracking tanks with an horchata mix?
