Air stones are sometimes frowned upon in planted tanks since the gas exchange at the surface can reduce CO2 in the water (and plants grow better with ample CO2). However, unless you're injecting CO2 it's a bit of a moot point and in the FW aquarium, there's nothing wrong with increased oxygen. Also, elevated temperatures typically means less oxygen dissolved in the water so in come cases, an air stone may be a benefit and since it can't hurt, why not???

@Deanasue doesn’t use CO2 to my knowledge.
