I have a 20oz brass and eagle tank and was wondering how to take it off a marker when it still has air inside it, thanks for any help :)

you just screw it off as fast as you can. There will be a burst of air when you do this its normal just keep turning till its out..

Dont go fast. Go slow but not stupid slow. There will be a puff of gas come out of the vent hole but that is cool.

Turn the tank a little (about 1.5 complete turns) and shoot your gun a couple times. If it still fires like it's aired up completely, turn it another turn and fire again. Keep doing it until it shoots itself down. Easiest and safest way to degas a gun, take a tank off and save your orings at the same time if you don't have an on/off ASA.

If it really bothers you, buy a new ASA (the thing your tank screws into) with and on/off valve. Most will vent the excess gas before you start unscrewing.

The tank. Either at the base or around the mid section.

Make EXTREMELY SURE that you're turning the valve with the tank, though. IF that comes off, the tank becomes a rocket - see California deaths a few years ago.

I stole some of my kids fingernail polish and painted a line across both the tank and the valve and let it dry. This way, I could monitor the tank and valve to make sure they stayed together. Safety first!

Man, I mention the word valve and the guy tries to kill himself. As viking said (or as viking likes it "viking is right"). always, always make sure the valve stays tightened to the bottle. It the bottle unscrews and the valve doesn't, call someone who knows what they are doing immediately!!!
