there is no such thing as "salinity in the air" salinity is the measurement of salt in water.... but anyways as everyone else has already said again and again whether its a small amount or large, your putting your T's at risk for no apparent reason and then acting like its helping them be healthier... and did you really say buying crickets from a frog guy was a bad choice because those crickets were fed to increase longevity in frogs??? come on man, are you trying to figure out the best way to keep your spiders alive or are you just trolling? you act like this is some "hot topic" but we are only trying to help make YOUR spiders happier and now it seems your just trying to get a rouse out of us all...
