Cloudy, Foamy, Or Bubbly Pool Water: What You Need To Know

Posted on: 25 November 2018

When you have a pool in your backyard, it will surely be enticing when the weather is hot, and the sun is bright. However, if you step up to the poolside and see anything other than crystal clear, welcoming water, it can completely change your desire to want to jump in. There are three primary problems that can come up in the water of a pool: cloudiness, foam, and bubbles. Take a look at some of what you need to know about the causes of each problem and how you should handle them. 

Why are there bubbles in your pool? 

If you go out to your pool and notice there are bubbles being pushed into the water from the return lines, it is usually because you have an air leak somewhere in the lines or components of the filtration system. The air could be slipping in through:

  • a leak around the strainer lid 
  • a bad pump seal in the water pump
  • a lower water level in the pool than usual

In most cases, these problems are easy to track down and diagnose. However, if you check everything and cannot find where the air is getting into the lines, it is best to reach out to a pool maintenance service technician for advice. There could be something more serious going on. 

What are the causes of foam buildup in your swimming pool?

Foam buildup can be an issue for some pool owners who have a major air leak. The air bubbles will accumulate to create a layer of foam that floats to the surface of the water. However, foam in the pool can also be caused by using the wrong type or an improper amount of pool chemicals. In either case, foamy pool water is not something that is normal, and foam can sometimes mean the pool is unsafe for swimming if the foam is related to improper chemical use. 

Why is your pool water looking cloudy?

Cloudy pool water is a typical problem if you are not using enough chlorine to treat the water. Chlorine kills off present bacteria, algae, and other water contaminants, so the lack of chlorine will leave the water looking cloudier than it should. The remedy to this problem is simple: check your chlorine levels with a testing strip and adjust accordingly. If the cloudiness does not clear up after chlorine treatment, there could be another issue at work.
