How Often Should You Change The Water In A Lay-Z-Spa?

Lay-Z-Spa hot tubs provide a luxurious and relaxing hydrotherapeutic spa experience, all from the comfort of your own home. This is all largely thanks to the power of water. Therefore, it is important to maintain your hot tub water quality and change it frequently. It is also important to understand when to empty your hot tub water and re-fill with fresh or what signs to look out for.

When Should You Empty Your Lay-Z-Spa Water?

Even with regular chemical treatment (we recommend ClearWater Chemicals) there will come a time when you need to change the water in your hot tub and replace it with clean fresh water. Sometimes the signs are clear, other times it is recommended to avoid struggling with chemical levels to keep the water quality and it becoming unenjoyable to use.

We recommend changing the water every 1-3 months and this depends a lot on the frequency of use and how effective chemical treatment has been.

Signs That Your Lay-Z-Spa Water Needs Changing 

Incorrect water treatment with hot tub chemicals can lead to a loss of water quality. Sometimes, water quality can drop even with regimented chemical treatment. But remember crystal clear water doesn't necessarily mean clean water. You shouldn’t always wait for any of these signs before changing your water, but if you experience any of the following, it is time.

• If the water develops a bad smell 
• When you lose water quality and it becomes cloudy 
• If it becomes difficult to balance chemical levels

Why do you need to change the water in your hot tub?

With a hot tub, it is important to remember that you are immersing yourself in the same body of water time and time again. Each time you use your hot tub tiny micro-organic contaminants are released into the water which can lead to bacteria lurking in the water. Over time, as explained below, it can become harder to maintain the chemical balance and water quality.  The only way to solve this is to empty and thoroughly clean your hot tub.

Why Change The Water Every 1-3 Months?

Supersaturation

Water can only hold so many chemicals before it becomes supersaturated. As you continue to add more chlorine, it will start dissolving slower and slower until it doesn’t dissolve anymore and it will become difficult to keep chemical levels balanced. Your Lay-Z-Spa water might start to get cloudy, you might even experience grit or scaling.

TDS (Total Dissolved Solids)

Over time, a hot tub’s water can develop high TDS (Total Dissolved Solids). TDS is the total of all dissolved solid matter such as organic matter, minerals, metals, salts and this includes chemicals too. This means that the body of water has reached its maximum capacity to break down and absorb any more chemicals.
