Chlorine demand of water too high at start up, after holidays or due to excess contamination or neglect In terms of numbers, 6 ounces of soda ash in a 10,000 gallon pool will raise the pH level by 0.2 with total alkalinity increased by only 5 ppm.

Start by testing the water (turn the jets off) using a testing kit. You can use test strips, a liquid test kit, or digital testing meter. These will all test for pH and TA levels. Take note of the pH level of the water. We’d recommend not doing this on a windy day (for obvious reasons), and you’ll have to test the water first so you can calculate how much baking soda is needed. The pH level of your pool water is a vital element of your pool's overall water chemistry. PH measures how acidic or basic the water is on a scale of zero to 14, with the ideal pH for swimming pools falling in the range of 7.2 to 7.6. When the pH level of your pool falls below 7.2, the water becomes acidic and can cause eye irritation, corrosion of metal pool equipment, dissipation of chlorine, etching of plaster walls and unsightly stains.


Low pH (more acidic) levels in water can lead to damage to the pool or hot tub – notably the grouting or plaster as well as any metal objects.

Soda ash will also raise the total alkalinity (TA) level. But when it comes to raising pH in a hot tub, you can’t raise one without raising the other simultaneously. Borax (sodium borate) is another powdery mineral that can be used to raise the pH level of your pool water. However, what it won’t do is affect the water’s alkalinity levels, which both soda ash and baking soda raise along with pH. 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. 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).A tub with a low pH level is bad news for bathers and for the tub itself. Here’s why you shouldn’t let the pH level stay low. In short, you can use either soda ash or baking soda to raise your pH level, but they will affect the pool water in slightly different ways. Soda ash is the preferred method to raise the pH of your tub. This is because soda ash, with it’s own 11.4 pH level, has the most drastic effect on raising pH.

It’s a popular method because it doesn’t raise the TA as much as soda ash will. However, the downside is that it’s not as effective at raising the pH.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. As a general guide, suitable dosage levels for spas sit at around 11 grams per 1,000 litres of spa water.

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. Baking soda (sodium bicarbonate) is also an alkaline substance, but with a lower pH level of 8 – commonly used to increase pH and total alkalinity. In fact, most pH Increaser products are just baking soda in a fancy bottle! 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. Allow sunlight exposure: Sunlight can help to break down and dissipate pool chemicals, which may contribute to a slight increase in pH over time. Make sure your pool gets adequate sunlight, but keep in mind that this method may not be sufficient to achieve significant changes in pH levels.Now that you know using something like soda ash to raise the pH can also bring up TA in a big way, you may need to lower it when retesting. 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.
