If bubbles are forming on the surface of the swimming pool water, one reason could be the presence of oil and grease on the water surface, while another reason could be the low calcium hardness of the pool water. These are the two main reasons for bubbles forming on the surface of the swimming pool water. If it is the former reason, please follow the method to address surface oil and grease issues. If it is the latter one, you can add food-grade calcium chloride to increase the calcium hardness of the pool water.

If you want to immediately address the unsightly appearance of surface bubbles, you can use BOWS™ Antifoamer product. Antifoamer can eliminate surface bubbles on the swimming pool water within 5 seconds, but it cannot break down surface oil and grease or increase the calcium hardness of the pool water.
