How Much Water to Put in a Bong: A Beginner’s Guide


If you are new to smoking herbs or tobacco with a bong, you might be wondering how much water you need to fill it with. The amount of water in your bong can affect the quality and smoothness of your smoke, as well as the ease of pulling it through the device. In this blog post, we will explain how to find the perfect water level for your bong, whether it has a simple downstem or multiple percolators.

Why Does the Water Level Matter?

The main purpose of using a bong is to filter and cool down the smoke from your herbs or tobacco before it reaches your lungs. The water in the bong acts as a natural filter that traps some of the tar, ash, and toxins from the smoke, making it less harsh and more flavorful. The water also cools down the smoke, which reduces the irritation and inflammation of your throat and lungs.

However, if you put too much or too little water in your bong, you might not get the optimal smoking experience. Too much water can make it harder to pull the smoke through the device, as you have to overcome the water pressure. It can also cause water to splash into your mouth, which is unpleasant and unsanitary. Too little water can make the smoke less filtered and more hot, which can hurt your throat and lungs.

How Much Water to Put in a Bong with a Downstem?

A downstem is a tube that connects the bowl where you pack your herbs or tobacco to the base of the bong where the water is. Some downstems have slits or holes at the bottom to diffuse the smoke into smaller bubbles, which increases the surface area and improves the filtration.

The general rule of thumb for finding the ideal water level for a bong with a downstem is to submerge the bottom of the downstem in about half an inch of water. This ensures that all of the smoke passes through the water and gets filtered and cooled. If your downstem has slits or holes, make sure that they are all covered by water as well.

To fill your bong with water, you can either pour it through the mouthpiece or directly into the base through the downstem hole. You can use tap water, but some people prefer to use distilled or filtered water for a cleaner taste. You can also add ice cubes to the water or the neck of the bong for extra cooling.

How Much Water to Put in a Bong with Percolators?

A percolator is an additional chamber or device inside the bong that further diffuses and filters the smoke after it passes through the downstem. There are many types of percolators, such as honeycomb, matrix, showerhead, tree, etc., each with its own design and function.

If your bong has one or more percolators, you need to fill each chamber with enough water to cover all of the openings of the percs. This ensures that you get maximum filtration and smoothness from your smoke. However, you don’t want to overfill your bong with water either, as this can create too much drag and splashback.

To fill your bong with percolators with water, you need to pour it through the mouthpiece and let it trickle down to each chamber. You might need to tilt or shake your bong slightly to distribute the water evenly. Once the water settles, check if all of the percs and downstem are properly submerged.

How Often Should You Change Your Bong Water?

Another important factor that affects your smoking experience is how often you change your bong water. As you smoke, your bong water will get dirty and cloudy from all of the residue and contaminants that it filters out. This can make your smoke taste bad and smell worse.

Therefore, you should change your bong water after every session or at least once a day if you smoke frequently. This will keep your bong clean and fresh, and prevent bacteria and mold from growing in it. You should also rinse your bong with hot water and clean it with alcohol or vinegar every once in a while to remove any buildup.


Finding the right amount of water for your bong is not rocket science, but it does require some trial and error. The best way to figure out how much water works for you is to experiment with different levels and see how they affect your smoke. The goal is to find a balance between filtration, cooling, and airflow that suits your preferences and needs.
