Why Won’T My PH Level Go Down In My Hot Tub?

How do I lower pH and alkalinity in my hot tub?

Start up the hot tubs pumps.

If you need to lower the alkalinity, add pH decreaser in the amounts shown on the back of the bottle.

If you need to increase the alkalinity, add total alkalinity increaser in the amount shown on the back of the bottle.

Let the water circulate with the pumps on for 5-10 minutes..

How do I lower the alkalinity in my hot tub without pH?

To raise low alkalinity and stabilize your pH, use sodium bicarbonate over a period of time. To lower high alkalinity, you can use a pH reducer or muriatic acid. Better yet, prevent mineral build-up and cloudy water from the start with ProtectPlus, which inactivates damaging minerals.

Is it safe to get in a hot tub with high pH?

You should NOT use your hot tub if the pH is too high (above 7.8). That can lead to itchy skin and burning eyes. But it can also cause scale build-up which can clog pipes and shorten equipment lifespans. If the total alkalinity is off, that can make it hard to balance pH.

Can I use vinegar to lower the pH in my hot tub?

How much vinegar should I put in my hot tub? By adding four cups of white vinegar or apple cider vinegar at a time and then allowing the tub to run through a cycle and circulate the pH can safely and effectively be lowered. Vinegar is one way to clean the jets.

What should be adjusted first alkalinity or pH?

Check Total Alkalinity (TA) first, then adjust for proper pH range. Proper TA will buffer pH, that is, it will help to prevent pH fluctuations. Use fresh, high quality test strips. Excessively high bromine or chlorine levels can result in false pH and TA readings.

Can I use pH down to lower alkalinity?

To lower both pH and Alkalinity you only need pH Decreaser, otherwise known as Dry Acid. Muriatic Acid, Acid Magic and No Mor Acid can also be used to lower Alkalinity and pH levels in pools. Add 1 lb pH Decreaser per 10,000 gals, to lower Alkalinity 10 ppm.

Will pH down lower alkalinity?

In other words, if you lower a pH of 8.3 to the recommended level using muriatic acid, the total alkalinity will also reduce but will still remain on the higher side. Likewise, if you lower alkalinity to the recommended level (e.g., from 300 ppm to 80 ppm), the pH level drops way below the recommended level.

How do I bring the pH down in my hot tub?

In order to lower both the pH and alkalinity of your hot tub water, you will need to add acid. Common choices are liquid muriatic acid or dry sodium bisulfate. When the acid is introduced to the water, it increases the hydrogen concentration and lowers the pH.

How do I bring my pH down?

To lower the pH, the most common liquid acid used is muriatic acid, also known as hydrochloric acid. To raise the pH, soda ash (sodium carbonate) is normally used. Sodium bicarbonate (baking soda) can be used to raise pH if the alkalinity is low, but it’s more commonly used to raise alkalinity.

What do you do if your spa pH is too high?

If you do encounter a problem with high pH, use a pH down product to get it back within the correct range. If your pH is too low, use a pH up product to raise the pH.

Does high pH cause hot tub foam?

A Bad Chemical Balance Can Cause Hot Tub Foam Water with a pH greater than 7.8 parts per million has too much pH, while hot tub water with alkalinity higher than 120 pm is too alkaline. Either problem can lead to cloudiness.
