Re: new to hookah
i'm going to assume he's using the standard small modern bowl i believe is what comes with that hookah, either 33mm or 40mm ql's, the standard metal tip chinese hose hose with a narrow gauge.
i had one of these, the only way to get moderate smoke from it is to make sure the water level is perfect, pack the bowl right, just sprinkle the tobacco in there (don't pack it tight because your draw will be horrible and restricted), and if you are using ql's break them into halves or thirds and put them at the edge of the bowl and rotate them as needed.
that's all I can say how to get decent smoke and a decent session out of it.
getting a new hose and bowl would really be pointless in attempt to get more smoke because of the narrow size of the hose port.
