How to measure and adjust the water level and temperature in your glass bong for optimal filtration and cooling?

If you enjoy smoking herb or tobacco from a bong, you may wonder how to get the best experience possible. One of the factors that can affect your smoking session is the water level and temperature in your bong. In this blog post, we will explain why these variables matter and how to measure and adjust them for optimal filtration and cooling.

Why does water level matter?

Water level is important because it determines how much smoke is filtered and how much drag you experience when inhaling. The water in your bong acts as a natural filter that removes some of the tar, ash, and other harmful substances from the smoke. However, too much water can also reduce the amount of THC and other cannabinoids that reach your lungs, as well as make it harder to pull the smoke through the bong.

The ideal water level for most bongs is just enough to cover the bottom of the downstem, which is the long tube of glass that sticks into the bong. This way, the smoke has to pass through a thin layer of water before entering the chamber, where it cools down and condenses. Any more water than that and you could get splashed while you’re smoking or waste some of your herb or tobacco.

How to measure water level?

The easiest way to measure water level is to use a ruler or a measuring tape. First, pour some water into the mouthpiece, which is the large opening at the top of the bong. Then, insert the downstem and check how high the water reaches on it. You can also look at the side of the bong to see where the water line is. Ideally, you want the water to be no more than 1 inch (2.54 cm) above the tip of the downstem.

If you have too much water, you can pour some out through the mouthpiece or the carb hole, which is a small hole somewhere above the water level that helps to clear the smoke when released. If you have too little water, you can add some more through the mouthpiece until you reach the desired level.

Why does water temperature matter?

Water temperature is another factor that can affect your smoking experience. The temperature of the water can influence how smooth and cool the smoke feels in your throat and lungs. Generally speaking, colder water will cool down the smoke more effectively than warmer water, making it less harsh and more pleasant to inhale. However, some people prefer warmer water because it can produce more vapor and flavor from their herb or tobacco.

The ideal water temperature for most bongs is around 50°F (10°C), which is slightly cooler than room temperature. This way, the water will not be too cold to shock your lungs or too warm to lose its filtering effect. You can also experiment with different temperatures to find what suits your preference best.

How to adjust water temperature?

The easiest way to adjust water temperature is to use ice cubes or hot water. To make your water colder, you can add some ice cubes to it before or after filling up your bong. Some bongs have an ice catch, which is a feature that holds ice cubes above the water chamber and cools down the smoke as it passes through them. To make your water warmer, you can heat up some water in a kettle or a microwave and pour it into your bong carefully.

Another way to adjust water temperature is to use different liquids instead of plain water. Some people like to use flavored drinks, such as juice, soda, or tea, to add some taste and aroma to their smoke. However, be aware that these liquids can also affect the pH and chemical composition of your smoke, as well as make your bong harder to clean afterwards.


Water level and temperature are two important variables that can affect how you enjoy smoking from a bong. By measuring and adjusting them properly, you can optimize your filtration and cooling for a smoother and more satisfying session. Remember to always use fresh and clean water for your bong and change it regularly to avoid bacteria growth and unpleasant smells. Happy smoking!
