How Long ?

[JohnBull]

Just had to drain my 50 gallon tank by 90 % so that we could move it to allow a new carpet to be fitted as it was far to heavy to move.
 
The filter was 'dry' for around 20 mins before we refilled it up and switched things back on. 
 
Is this a sufficient period to have killed all my good bacteria in my tank ?

No, they'll be fine, but it would be wise not to feed for a day or two, and do extra water tests, or water changes, just to be on the safe side.

Phew...thanks.
 
Is it true you should always remove ALL the gravel before moving a tank,cos we have to replace the tank in it's original position next week ?

The only reason I would do that would be to make the tank lighter and easier to move. As long as you're not going up or down stairs which would cause the gravel to shift and scratch the bottom of the tank, you should be fine. If you're just moving it from one room into the next room (And you and the person moving it are close to the same height) then leaving the gravel in is alright.
