I just bought a Azoo indicator. There seem to be more than one
version of it, so click this link to see the one I have.

Anyway, It is not clear to me from the instructions which way the
thing is to be orineted in my tank. Is is open end down, or open end
up?

If it is open end down, Should there be a trapped air bubble between
the hole leading the indicator fluid or should I let it escape? That
would seem that the indicator fluid with just leak into the tank.



Any help would be appreciated.
