Have you have ever lifted your hot tub cover and discovered fluffy, puffy foam floating on top of your water? Though foamy water is not what you want to see in your backyard retreat, normally the solution is a relatively simple fix. But how do you get rid of it?!
3 Common Culprits of Foamy Water
There are 3 common culprits of foamy water: personal care products, problems with pH and low calcium hardness. Using products to decrease the foam are a very short term solution. Fix the underlying problem.
Personal Care Products
Let’s talk about personal care products and soap residue on bathing suits or skin. They can dissolve into the water and cause it to be frothy. (Ewww ….) Oil from lotions, hair products, makeup and sunscreen can be the culprit too. It sounds kind of strange, but we recommend not using detergent when washing swim wear and make sure to rinse it very well.
High pH? Low pH?
High pH in hot tub water can cause the appearance of foam on the water. Testing your water regularly with test strips help determine if any balancers are needed.
pH Decreaser or pH Increaser
To correct a high pH in your water level, add pH Decreaser such as our Waters Choice pH Down product. To bring the pH back into the normal range, or if your spa water has a low pH level, use Waters Choice pH Up.
Low Calcium Levels
Low calcium hardness levels can also bring about foamy water. Besides the fact that low calcium is very hard on your hot tub’s parts, it also lowers the surface tension of the water which creates perfect conditions for lathery water.
If, after testing your water, you discover the calcium is low we find that using a calcium increaser will help you bring your spa back to healthy levels. Unfortunately, when your calcium levels are too high it can be difficult to lower them. Just drain it. Trust us. Clean the hot tub using vinegar or other products that will remove calcium from the inside walls of your hot tub.
Ion Exchange Pre Filter – Yes!
Then, when refilling the water, use our new Ion Exchange Pre-Filter to filter out mineral including calcium. Don’t forget that using test strips that include calcium hardness will help you maintain and check the levels in your spa.
Always Start With A Test Strip
Whatever your water issues are, start with a water test using a test strip is a good place to start. Determining that your levels are correct helps to narrow down what is happening in your spa.
