Re: acclimating hookah...
Acclimating washed brands, Starbuzz, Fantasia, Epic, etc. is pointless. Tangiers is the tobacco that always needs to be acclimated, but since you seem very new to the hookah culture, you most likely havn't heard of that brand. Al Fakher is common, but doesn't need acclimation to adjust flavor, only very rarely and in most cases your attempts will be fruitless. Al Amir doesn't need it, nor does Nakhla.
You might just have a dirty pipe.
