Can I raise the alkalinity in my hot tub?

• <div><p>Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.</p></div>

Q: What temperature should a hot tub be kept at when not in use?

• <div><p>When your hot tub is not in use, you can keep it at a constant soaking temperature of around 100 degrees Fahrenheit. For extended periods of non-use, you can lower the temperature by about five degrees. This slight decrease makes it easier and quicker to heat back up to a desirable level when you're ready to use it again. Additionally, you might consider lowering the temperature by a couple of degrees during the summer to avoid feeling overheated.</p></div>

Q: Can professionals diagnose and repair pool equipment issues?

• <div><p>Yes, they provide full-service inspections, identifying and resolving any potential equipment problems.</p></div>

Q: Can a crack in a hot tub be repaired?

• <div><p>Most hot tub cracks can be repaired unless they have gone beneath the acrylic. If so, you may need a professional to determine if the crack is repairable or if you should consider hot tub replacement instead.</p></div>

Q: Is it more cost-effective to leave a hot tub running all the time?

• <div><p>Generally, it is more cost-effective and energy-efficient to leave your hot tub on all the time rather than turning it on and off. Reheating a hot tub from a cold temperature consumes a significant amount of energy, so maintaining a constant temperature is usually more economical, especially with frequent use.</p><p>For daily or weekly use, it's recommended to keep the water at a constant, reduced temperature, such as between 80 and 95 degrees Fahrenheit, and then increase it to your desired temperature before getting in. If you know you won't be using the hot tub for an extended period, you can lower the temperature to save on energy costs. However, if you use it very infrequently, you can turn it off completely, as long as there is no risk of the water freezing.</p></div>
