Diaphragm Tank Life -Ed

After only 5 years my closed system diaphragm expansion tank appears to be unable to hold air pressure over 5lbs.?
Before I purchase a replacement what manufacturers hold up better and can handle Cryotek Antifreeze? I suspect the antifreeze shortened the life. Would appreciate hearing some solid advice from the pros. Thanks to all.

    If it will hold any

    air pressure at all maybe the diaphragm is OK. Do you get fluid out the air charging valve? Is the Schrader valve in tight and not leaking? For use with glycol solutions, use a tank with an EPDM diaphragm, and if you have to add air, use an oil-less compressor or oil-free air.
