Re: What the hell is up with my hookah?
It could also be the bowl; not just in the sense that you need a new one. As bowls get used more, black gunk tends to accumulate inside around the rim. This can muddle the flavors.
There are two ways to get rid of the gunk. One way is to fill a *** with water and your bowl, and set it to boil. The boiling water will loosen it up enough to get rid of it.
The second way is to take a piece of very fine steel wool or sandpaper and just scrub out the gunk. Both ways work well. Try this before buying a new bowl, and see if that clears up your problem. As you've had good luck with this bowl for a while, it doesn't sound like you quite need a funnel bowl—though it's an excellent purchase regardless.
