Ok so I just had got this very nice double matrix Perc straight tube glass piece for my yabba dabba do’s. My problem is although an experienced smoker/glass lover, I’ve never quite come across the problem i set before my fellow foe. So i was filling my bong up to the correct water level (i thought), when i noticed the second level was not holding water tag least not enough to cover the entire Perc, no is this just an error within the glass or do i have to fill this thing with an excessive amount of water just to recoieve a little second level Perc. Ill show you just how much water i need to receive that filtration in the pic. Please anyone?
