Shops do not often make their policies known. That is why the diver has to take some initiative and ask. There is no such thing as an air or nitrox cylinder. No difference in price. It is what is done to them in the store that makes em air or nitrox. And you can put air in any nitrox tank. And if it's O2 compatible air you do not have to clean the tank to go back to nitrox. Anyone who says you cannot put air in a nitrox tank is an idiot. And you don't have to empty the tank. It's a good idea to analyze the fill if you plan on doing any deep stuff with it. And if the shop banks their nitrox you don't even need a nitrox tank.
My best air fill was topping off a set of doubles that had been filled with 21/28 trimix and ending up with about a 10% he mix as I recall. Saw things in the local deep hole with more clarity than I ever had before.
