I have a 2 Gallon Betta Tank In My Office. I am using our drinking water cooler for water changes. Should I still use some sort of conditioner or is drinking water ok to just put in there?
"drinking water" can vary wildly from brand to brand depending on where it was bottled...It may also be distilled, lousy for your fish...Stick with treated tap water

Distilled and R/O water have no minerals, which are necessary for fish health. Those minerals can be added back in with commercial products, but for most aquarists, tap water is an easier (and cheaper) choice.
