Facebook Lives


Facebook Live — May 7, 2025

Owning a swim spa means more than just relaxing or swimming at your convenience. It also means taking care of the water. One of the most common questions swim spa owners ask is: Do I really need to change the water every six months?

In this Facebook Live replay, Master Spas experts Ben Gilliam and Mari Cuticelli talk about why water changes are essential for keeping your swim spa running properly and feeling great to use. While six months is a general recommendation, they explain that the real answer depends on how often you use your swim spa and how well you're able to maintain the water balance.

There are typically two ways people approach changing their swim spa water. The first is proactive maintenance, where you drain and refill before you run into any issues. The second is reactive maintenance, where you wait until the water becomes cloudy, harder to balance, or starts using more sanitizer than normal. If you're struggling to keep your water clear or find yourself constantly adjusting chemicals, it's a good sign that it's time for a fresh start.

Ben and Mari also walk through the step-by-step process of draining and refilling your swim spa. They answer common viewer questions like:

Do you clean the tub before refilling? Yes, and they explain what kind of cleaner is best for the job.

What chemicals should you have on hand? You'll want to have your startup chemicals, including Metal Protect, ready so you can balance the water right after filling.

What's the best type of sump pump to use? A sump pump can help drain your swim spa quickly and efficiently. But it can feel overwhelming to compare options at a hardware store. They give tips on what to look for, especially if you want the job done efficiently.

How long should you wait to use the spa after filling it? They talk through timing and why it's important to make sure your water is safe before getting back in.

Where do you drain the water if you live in a neighborhood? It might be tempting to drain your spa into the street or into a nearby storm drain. But, depending on your neighborhood, it might not be the best option.

Whether you're a new swim spa owner or have had your Master Spas model for years, this video is full of practical advice to help you feel confident in your water care routine.

Remember, changing the water isn't just about looks. Iit's about performance, safety, and getting the most enjoyment out of your spa. Clean, balanced water helps your spa components last longer and keeps your swim experience as enjoyable as day one.
