Is this possible? I see guys with CCRs dive it in their dill but with my mix calculator I don't see how it is possible with a partial blend? It says they have to remove -15 02 PSI.
I'm assuming they just drop the helium in the tank and top with air? The -15 02 is too small or is there another way they mix this.
