Hello Cynthia! Thank you so much for your fantastic review! We're delighted to hear how much you love your hot tub—especially the jets and your quick heating routine. It’s wonderful to know it’s become a part of your relaxing weekends! To help you and other spa owners get the most out of your experience, here are a few important tips to ensure optimal performance and longevity: 🔹 Temperature Guidelines: This spa cannot be used in temperatures below 32°F (0°C). In ambient temps above 30°F (-1°C), it can heat up to 104°F (40°C). In colder conditions (below 30°F), the max safe heating limit is 90°F (35°C). Important: Always keep the insulated cover on when heating or not in use—this traps heat, speeds up warm-up time, and saves energy. 🔹 Water Level Maintenance: Always keep water between the MIN and MAX lines—if it’s too low, heating will not function properly. 🔹 Filter Care: Replace the filter every 168 hours of use to maintain clean water and efficient operation. 🔹 Bubble Function Safety Feature: The bubbles will automatically pause after 20 minutes (10-minute cooldown) to protect the system. This is not a malfunction—simply wait 10 mins and press the button again to restart. If you ever have questions or need assistance, our support team is happy to help yours. Enjoy your soothing soaks, and thank you for choosing us! 💙
