Your product will always taste the best if you are using clean water in your bubbler. Our products usually taste the best when you change the water after four full uses (bowls). After about four full uses (bowls) the water will start to look discolored and may appear thicker (more viscous). That's when you know its best to change out the water.
You should set aside any removable pieces before pouring out the bubbler because the liquid can be unsavory. Be sure to keep the water running to dilute the liquid when it's being poured out. Remember that this liquid contains any harmful substances that the water helped filter out.
Now rinse the bubbler out with fresh water and then fill up to the proper level.
After placing the removable pieces back, you should be finished!
