Bong & rig questions
How much water should I put in?
Enough to cover the downstem slits by about half an inch. Too little = no filtration; too much = splashback into your mouth. Test by inhaling gently before lighting.
How do I clean it?
Empty water after every session. Deep clean weekly with 91%+ isopropyl alcohol and coarse salt — see our 7-step bong cleaning guide. Don't pour boiling water on cold glass — borosilicate is heat-resistant, not heat-proof.
What's a percolator and which is best?
A percolator is the part that diffuses smoke into water for cooler, smoother hits. Showerhead, tree, honeycomb, and recycler are common. Recycler is the smoothest; showerhead is the most balanced. Read the bong shape guide for the full breakdown.
Will my existing bowl/banger fit?
Match joint size and gender (male/female). Most modern rigs use 14mm female. Read the joint sizes guide if unsure.
