Your hot tub is a place of relaxation where you can forget about the cares of the world. If you’re using APi products to maintain your spa, you have even more time to enjoy it. But how often are you changing the water in your hot tub?  Is it enough, too much, or have you just flat out never done it? In this article, we will discuss some ways to determine how often you need to drain and refill your hot tub.

The process of changing the water in your hot tub is quite simple as the formula to determine how often you need to change it. Many people believe that the frequency for changing the water in your hot tub is most directly related to the frequency of usage. While it is true that if you use your hot tub less, you should change the water less, this is not the end of the discussion. It does play a part in determining how often you change the water, but there is another important formula to consider.

The general rule of thumb when it comes to calculating how often to change the water in your hot tub is to divide the total number of gallons of your hot tub by 3, and then divide it again by the number of daily users. This formula will give you an approximation of the number of days that you can go between changing the water in your hot tub. For example, if you have a 480-gallon hot tub and have 3 average daily users, you should be changing the water in your hot tub approximately every 53 days.

This formula is not a hard and fast, set in stone rule when it comes to changing your hot tub water. There are some other things that you should look out for to keep your spa in optimal operating order throughout the year. If you notice that the water in your spa is cloudy and shocking it doesn’t seem to clear it, it’s time to drain and refill. If you are developing a lot of foam and the defoamer isn’t having an effect, it is also likely time to change the water. The most noticeable sign that it is time to change the water in your hot tub is if the water begins to smell. A foul smell is a sure sign that you are overdue for changing out the water.

We hope that these guidelines help you to keep your hot tub clean, clear, and inviting all year. Another great way to do that is by using the EZ Spa Care Kit line of products to maintain your hot tub. You can learn more about how these products can save you time and money here.

  • “Just wanted to thank you for a great product. After four weeks of trying several different products and also adding way to much chlorine, we can finally see the bottom of our pool. Added REVIVE! at 6PM last night, by the time we went to bed, we could notice a difference and when I got up this morning everything had settled to the bottom. Used the vacuum for about an hour this morning and were swimming this afternoon. Will probably have to vacuum once more, but so glad this product was recommended to us.”

  • “Easy, simple, worry free…these all describe how my pool maintenance has been since I started using EZ POOL! I have a big pool and it is not a big job with E-Z POOL, just once a week. Once the pool is open and clear in the spring, I just have Caryl’s experts test my pool sample once a week to make sure the balancing chemicals and pH are good. Algaecides are not needed. Brush, brush, brush, as Caryl recommends and my pool is beautiful all summer! Also, it is gentle to the skin and does not effect your hair color. I highly recommend E-Z POOL!”

  • “I have used the EZ Spa now for four years. It is the best spa treatment I have ever used. It makes the water feel really soft and refreshing. I use it once a week and forget it. My spa stays crystal clear. I love this stuff. Not to mention when you use EZ Spa you don’t have to buy so many other chemicals. I also noticed that EZ Spa is extremely gentle on the skin. I can’t say enough about how good this stuff is. Try it, you’ll love it!”
