Product Information

Here’s everything you need to know about hot tub chemistry. Discover the chemicals you need to add to your home spa to keep it hygienic. 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: are " conservative" such that they are unaffected by changes in temperature, pressure or pH. [8] Others such as HCO − Measuring your spa’s Total Alkalinity once a week will help you catch a significant increase before it becomes a problem. What causes low alkalinity in a hot tub? You’ve made a mistake: It could be something as simple as using too much baking soda or other alkalinity increaser product.

Once you’ve added the alkalinity increaser or pH decreaser, test your hot tub’s water again. If the TA still isn’t within 125 and 155 PPM, adjust until it is.

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. 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. 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 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. 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.

Although alkalinity is primarily a term used by limnologists [5] and oceanographers, [3] it is also used by hydrologists to describe temporary hardness. Moreover, measuring alkalinity is important in determining a stream's ability to neutralize acidic pollution from rainfall or wastewater. It is one of the best measures of the sensitivity of the stream to acid inputs. [6] There can be long-term changes in the alkalinity of streams and rivers in response to human disturbances such as acid rain generated by SO x and NO x emissions. [7] History [ edit ] 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 upWhen 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?

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.

In freshwater, particularly those on non- limestone terrains, alkalinities are low and involve a lot of ions. In the ocean, on the other hand, alkalinity is completely dominated by carbonate and bicarbonate plus a small contribution from borate. [4]Alkalinity roughly refers to the molar amount of bases in a solution that can be converted to uncharged species by a strong acid. For example, 1mole of HCO − Corrosion issues: Even if your hot tub is fibreglass, corrosion can still be an issue. However, it’s even more serious if your hot tub has a metal surface. It can also be detrimental to the internal workings of the pump and its filter. Corrosion issues could mean your pump and its filter will need to be replaced, which would be very costly. If the total alkalinity is low then the pH can fluctuate making it difficult to control and maintain at the ideal level. 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.

pH is measured on a scale from zero (acidic) to fourteen (alkaline), with seven being neutral. Your hot tub’s water needs to be between 7.2 and 7.6 pH at all times. Test your spa’s Total Alkalinity once a week as part of your hot tub maintenance routine, add a few scoops of chemicals if they’re needed, and then finish off by adjusting the pH.

These compounds attract and release Hydrogen ions, which neutralise acid in your spa’s water and increase its pH level. Why is your hot tub’s Total Alkalinity important? Use the same amount of soda ash as you would baking soda. In other words, one tablespoon for one hundred gallons of water. Be sure to carefully measure out the chemical you need before adding it, as you need to be precise to get the right results. Find the best hot tubs across every price range with the WhatSpa?
