I just bought the Bio-Filter. Can the charcoal filter be used with nitrox 32 or 36? If not, why not? I read the user instructions and nowhere does it say to remove the charcoal filter when using nitrox. It does state "Remove the charcoal filter for diving in excess of 130 feet. The system is not for use with nitrox above EAN level 40". I'm a bit confused because I've been reading posts which say to remove the charcoal filter when using nitrox.
