Total Alkalinity Increaser raises the alkalinity of your hot tub water.

Total Alkalinity Increaser

Increases the alkalinity of the hot tub water, which is critical to control pH levels and prevent equipment corrosion.  A range of 100-150 ppm should be maintained at all times.

Alkalinity is raised with Alkalinity Plus and can be reduced with pH minus.

Test for total alkalinity with a reliable test kit. The desired range for total
alkalinity is 80-140 ppm.
This product increases the effectiveness of the disinfectant, and helps prevent
scale formation. It also prevents corrosion of metals, etching of spa surfaces,
eliminates “bounce”, and maintains pH at the proper level. Easy to use;
dissolves quickly.
1. Add 1 oz. (2 tbsp) to pool or spa water.
2. Allow water to circulate for 30 minutes.
3. Retest water and repeat steps 1 and 2 until the desired level is reached.
For best results, dissolve granular products first by adding to a small plastic
pail filled with water.

What is Total Alkalinity?
Total Alkalinity is one of the least understood yet most important component of keeping water chemistry in a hot tub balance.

Total Alkalinity (TA) is the buffer of pH in a hot tub.  This means if this measure is out of line, the pH readings may be off and pH may fluctuate more wildly, causing problems getting pH to balance in the 7.2-7.6 range.

Total Alkalinity readings should be between 80-120 parts per million (ppm).

Note that pH minus will lower the total alkalinity as well.

Side effects of Total Alkalinity out of balance

If TA is too high, then the sanitizer has to work harder, skin and eye irritation can occur, cloudy water and scale can form and the pH will be hard to control.

If TA is too low, then quick changes in the pH level can occur, corrosion and damage to seals and equipment are possible and skin/eye irritation can occur under acidic conditions.
