I find that air bubbles keep getting in the "pointer" and giving me false
readings. How do you fill the darn thing without getting air bubbles?

I know you can tap the hydrometer to get rid of the bubbles, but
some just wont go away.

It usually happens when the hydrometer is "too clean"
or "dry". Keep new hydrometer with water for 24 hours
and it should develop some minimal bacteria film maybe?
or something like that to make it "less dry" and more
slippery for the air bubbles :-)
It will get better when you use more often and longer.

Also - there is a smart hydrometer called Deep Six
which has a nice design with a little dam and water
gets in slowly falling/sliding on the inner wall,
not causing any bubbles to develop...
