Reasons For Cloudy and Foamy Hot Tub Water

Foam and cloudy hot tub water is a common issue many owners run into. This can be frustrating because it can result from many different factors. Since hot tubs have a low volume of water kept at high temperatures, this impacts the contaminants that come into the water. These contaminants can be from nature such as leaves, or even from the users such as hair or body oils. If you want to learn why your hot tub water gets cloudy and foamy then keep on reading. 

What causes the foam?

A buildup of foam on the surface of the hot tub water is usually due to a reaction between the alkalinity of the water and any oils brought into the tub. Although these elements are mostly invisible, they collect together over time to create foam once you turn on your jets. The oils and impurities that are most commonly brought into the water are makeup, body lotions, suntan lotions, detergents, fabric softeners, soaps, and hair products. 

How To Eliminate Foam 

The product you should try is using an all-natural enzyme solution. Enzymes will speed along the removal process of organic contaminants. If this fails your last resort should be to completely flush and then drain the hot tub.

What Causes Cloudy Water?

There are a number of factors that can contribute to cloudy water. One of the factors is if the water has a high alkalinity or PH readings. If the alkalinity is too high, carbonates can fall out of the solution and cause cloudiness. Filters are also a major factor in cloudy water. A buildup of materials in the filters prevents it from working efficiently. Minerals can also be another factor. When minerals and chlorine, bromine, or shock are combined, the minerals in the water begin to oxidize, or rust. The result is discolored cloudy hot tub water after shock that often appears green or yellow.

How to Eliminate Cloudy Water 

The best thing to do is check your water chemistry and then adjust it as needed. You should also check your filter and replace it if needed. When filling your hot tub as needed it is best to use clean filtered water, this will help prevent the water from becoming cloudy. If all else fails, the last resort should be to completely flush and then drain the hot tub. 

How To Prevent 

There are some preventative measures you can take to ensure this doesn't happen. Replacing and cleaning your filters regularly is best. If they aren’t cleaned or replaced regularly it can get clogged and then the hot tub water gets cloudy. Make sure it is cleaned frequently especially when it is not in use. If not cleaned algae can grow and build up quickly. Debris will also fall into the hot tub and this can clog the jets and make bacteria grow faster. One more important preventive you can do is to balance your chemical levels. 

Conclusion

In conclusion, by proactively taking care of your hot tub water, you’ll be able to enjoy your hot tub all through the year without any unpleasant foamy or cloudy surprises waiting for you. It’s important to check your hot tub frequently to avoid this and maintain proper hygiene standards as well.
