Work out the amount of sodium bisulfate needed. It depends on the volume of water in the hot tub and how much you need to lower the TA. As a guide, 3.5 ounces of sodium bisulfate will lower the TA of 1,000 gallons by around ten ppm. If your hot tub only contains 500 gallons, you’ll only need to add 1.75 ounces to lower the alkalinity by ten ppm. Skin irritation: The hot tub water becomes very acidic when the alkali levels are low. Anyone soaking in the tub will find this very irritating for their skin, nasal passages, and eyes. It could even lead to respiratory distress. are affected by changes in pH, temperature, and pressure. By isolating the conservative ions on one side of this charge balance equation, the nonconservative ions which accept or donate protons and thus define alkalinity are clustered on the other side of the equation.
Hot tub maintenance won’t take up too much of your time once you’re up to speed. Read our complete guide to hot tub maintenance now. Measure out the correct amount according to your calculations. Generally, you’ll need one tablespoon of sodium bicarbonate if your hot tub contains 100 gallons of water. Once your spa’s Total Alkalinity is in balance, test its pH and then use pH increaser or decreaser to get that within 7.2 and 7.6. Fluctuating pH levels: When there is insufficient alkalinity in your hot tub water, it means the pH level will fluctuate wildly. This is known as the pH bounce. It happens because the water has an insufficient pH buffer.Refer to the manufacturers’ instructions to see how much alkalinity increaser or pH decreaser you’re going to need to add to your spa to get the TA right. Your hot tub’s Total Alkalinity is the amount of dissolved alkaline compounds – like bicarbonate, carbonate, and hydroxide – in its water.
When you’re adjusting your hot tub’s chemicals, you should always get the TA dialed in first, then adjust the pH. If the TA isn’t within the right bounds there’s no chance the pH will stay stable. What’s the right amount of Alkalinity? Please note some areas including Scotland(post codes AB, FK, IV, KW, PA, PH, HS, KA, ZE, TR, DD,PH, PA, KY, AB, DD, KW, IV, HS), Isle of Wight, Isle of Man, will need extra carriage. We no longer ship to Jersey, Guernsey or Northern Ireland.You should test your hot tub’s TA once a week. If it’s below 125 PPM, you can increase it with an alkalinity increaser. If it’s above 155 PPM, you can decrease it with a pH decreaser, as decreasing the water’s pH will lower its alkaline concentration. What causes high alkalinity in a hot tub? Not to be confused with alkali or base (chemistry). Sea surface alkalinity (from the GLODAP climatology). Testing your hot tub’s Total Alkalinity each week will help you catch a serious dip before it starts causing headaches. How to adjust your hot tub’s Total Alkalinity If the total alkalinity is low then the pH can fluctuate making it difficult to control and maintain at the ideal level.
If the total alkalinity is high then the pH can be difficult to change and will keep rising. A high total alkalinity can also lead to the formation of a bicarbonate scale on pool surfaces, within pipework and in plant room equipment. If your spa’s Total Alkalinity is too high, its water will be too alkaline. As well as stopping your sanitiser from killing bacteria as effectively as possible, alkaline spa water will also: If your spa’s TA is too high, it’s pH levels will be sky high and just about impossible to keep below 7.6. If it’s too low, the water will be far too acidic and difficult to bring up to 7.2. conservative cations ) − ∑ ( conservative anions ) = [ H C O 3 − ] + 2 [ C O 3 2 − ] + [ B ( O H ) 4 − ] + [ O H − ] + [ H P O 4 2 − ] + 2 [ P O 4 3 − ] + [ H 3 S i O 4 − ] + [ N H 3 ] + [ H S − ] − [ H + ] − [ H S O 4 − ] − [ H F ] − [ H 3 P O 4 ] − [ H N O 2 ] {\displaystyle {\begin{aligned}&\sum ({\text{conservative cations}})-\sum ({\text{conservative anions}})=\\&\quad [\mathrm {HCO_{3} Your hot tub’s Total Alkalinity and pH levels are both closely linked.

Before you get in your hot tub, test its TA and pH levels again to make sure they’re where they need to be and adjust again if necessary. Summing up Too many chemicals: If you add more chemicals than you need to, it will increase the TDS or Total Dissolved Solids. You must drain, clean, and refill your hot tub once every quarter to stop this from happening.
