First, you need to add a pH down product, also known as pH decreaser (all basically types of acid). After adding the pH down, test the pH level again to ensure it has been lowered to the desired level. Make sure that any outdoor storage of chemicals is as far away from your hot tub as possible and in a dry, covered area. Humidity or even small amounts of water can cause chemical reactions that could lead to dangerous fumes. It's important to regularly test the pH level in a hot tub and make adjustments as needed to keep it within the desired range. If you are unable to lower the pH level despite adjusting the TA, you may need to drain and refill the hot tub with fresh water. Sometimes it's better to just start over. What causes high alkalinity in a hot tub? This is also called the self-ionization of water. The concentration of \(H_3O

After 30 minutes, you should re-test to make sure the pH has been raised to at least 7.2. How to raise alkalinity without raising pHFor low pH levels below 7.2 you will need to use pH Plus to help raise the pH levels and balance the water.

For low TA levels below 80ppm you will need to use Total Alkalinity Increaser. The amount of TA + you need to add to your hot tub depends on the volume of water and how low your readings are. As a guide - a hot tub of 1,000 litres requires 18g to raise Total Alkalinity levels by 10ppm (parts per million). The amount of pH increaser or decreaser you need to add to your hot tub depends on the volume of water and how low your readings are. Refer to the dosage information will be printed on the individual chemical bottles.When you’re ready to begin mixing your chemicals, you should handle them with chemical resistant gloves. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation. It is also advised to wear tightly sealed goggles and appropriate protective clothing such as long sleeves, trousers, and closed-toed shoes that fully protect your feet from spills. You should also wash your hands after handling chemicals. newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\) Please note: This guide is only applicable to Clearwater Chemicals. If you are using other chemicals, dosages may vary. Dosages are only approximate depending on the exact amount of water in your spa, water type, water temperature, positioning of the spa, bather load, weather etc. Lay-Z-Spa Model Do not eat, drink or smoke when using this product. Have a First Aid Kit available for any accidents The 5 Inch Chemical Floater slowly releases Clearwater Mini Multifunctional Tablets or Chlorine Tablets, making it the perfect accessory for busy spa users who want a hassle-free way of maintaining clear and healthy spa water. The dispenser has an adjustable dial which controls the release of the 20g tablets, ensuring that the sanitizer level of your spa water is consistently and efficiently maintained. Compatible with all spa models.

Heavy hot tub usage: Again, hot tub usage can also cause the pH level to drop due to contaminants such as sweat, oils, and lotions that are added to the water by bathers. These contaminants can lower the pH level.This TA Increaser helps raise Total Alkalinity levels, which in turn will help control pH levels and chlorine. Remove cover from pool to allow evaporation of the chemical (keep the pool filter running constantly). Clearwater pH Plus , also known as ‘pH increaser’ is the best way to increase pH levels that have dropped below the recommended level. To avoid skin discomforts and enable the chlorine in your spa to work effectively, it’s vital that acidity is monitored and controlled. The recommended pH balance of spa water is between 7.2 and 7.6. Dissolve the quantity of Chlorine Granules in a jug of warm water and pour into your hot tub. Activate the AirJets for a few minutes to circulate the chemicals evenly throughout the water. Dip a ClearWater® Test Strip in the centre of your Lay‑Z‑Spa, remove and hold it still for 15 seconds.
