No it's not what you may think.
i also have some air plants. Those who have them know that periodically you have to soak them in water to prevent them from drying out.
You can use just tap water. but, one of the best waters to use is aquarium water. Among other plant nutrients it contains needed nitrates.
"Air plants aren't too picky when it comes to water, and most tap water is just fine, but it depends on the water quality in your area. The best water to use: rain water, aquarium water, or pond water because these are more rich in nutrients (note: if using one of these waters, don't add any additional fertilizer) "
So, when doing water changes when they are due for soaking, save some to soak your air plants in .
