Maintaining the perfect balance of your hot tub water’s chemistry is not just about ensuring a comfortable and safe soaking experience; it’s also crucial for the longevity of your hot tub. One of the key aspects of water balance is managing the total alkalinity. High alkalinity can lead to cloudy water and scaling and even affect your sanitizer’s efficiency. Here’s a step-by-step guide to lowering the alkalinity in your hot tub efficiently and safely.
A high alkalinity level can also cause green water; nobody wants to get into a green hot tub. High alkalinity can also cause very high pH, which can result in calcium buildup or scaling; you might be used to this in your kettle when used for a long time. Calcium buildup can show as yellowish flakes, which are unappealing to the eyes and can clog up jets and damage equipment if they are not dealt with. Lastly, high alkalinity can cause your sanitizer to not function properly as it is designed to be used in water with a balanced alkaline level.
As you can see, alkalinity balance is essential for your health and your hot tub’s health, but how do you lower that alkalinity if it’s too high? Here are some simple steps on how to lower your alkalinity levels.
Step 1: Testing The Water
Start with testing the water using a reliable test strip or a liquid test kit. Accurate readings are crucial for determining how much alkalinity decreaser you’ll need to use.
Step 2: Turn Off The Hot Tub
Ensure your safety and the effectiveness of the treatment by turning off the hot tub before adding any chemicals.
Step 3: Choosing The Right Chemicals
Alkalinity can be reduced using a hot tub-specific alkalinity decreaser, commonly found in the form of muriatic acid or sodium bisulfate. These are often available at pool supply stores or online.
Step 4: Application Process
After turning off your hot tub to halt water circulation, carefully add the decreaser following the manufacturer’s guidelines. The amount needed will depend on your hot tub’s volume and the current alkalinity level. Distribute the decreaser evenly in the deepest part of the hot tub.
Step 5: Waiting Game
Once the chemical is added, wait for about 30 minutes to an hour to let it disperse properly. During this period, keep the hot tub off to prevent disturbance in the water.
Step 6: Circulation
Turn your hot tub back on to circulate the water. This helps in evenly distributing the chemicals throughout the tub.
Step 7: Re-testing
After a few hours, test the water again. If the alkalinity is still higher than desired, repeat the process, but ensure not to overdo it as drastically lowering alkalinity can lead to corrosive water.
Step 8: Balancing pH
Lowering alkalinity can also affect the pH levels. After adjusting alkalinity, always check and adjust the pH level to maintain it within the ideal range of 7.4 to 7.6.
Step 9: Regular Maintenance
Regular testing and adjustment of your hot tub water are essential. Keep a consistent schedule to ensure your hot tub’s water stays balanced and ready for use.
Always handle chemicals with care. Use protective gear like gloves and goggles, and follow all safety instructions on the product labels.
