The small sapphire I'm using doesn't have enough power to fix these problems so while traveling I'll need to keep the flask and gem as still as possible to avoid any problems, the final enchantment I add is a spell that purifies water this spell takes a decent amount of magic as it uses a fair few symbols but I solved that by making it only purify water in a very small area the inside of the flask, and the spells can purify my flask in only a few seconds as the spell may take a decent amount of magic but is fast working.
