- Increases Total Alkalinity
- Come in 750g bottle
Why
- Raises Total Alkalinity (TA) of hot tub water
- Use when TA is less than 125 ppm to return to effective range of 125 – 150 ppm
- Low TA causes;
- pH bounce – difficult to balance
- Increased corrosion of metal surfaces- staining
- Etching of plaster, grout
- Increased risk of problems and major repair costs
- Highest grade mineral available
- Very fine, granular form
- Dissolves quickly and fully
- Food grade – no impurities
- Alkaline – pH 8.3 in solution
- Apply when needed to maintain TA between 125 – 150 ppm
- Always test with fresh fill and monthly thereafter
How Much
- To raise TA:
o 18 g per 1,000 L raises TA 10 ppm
- 1 capful = 10 grams (approx.)
How
- Always adjust TA 1st, before pH or TH
- Operate pump with air off
- Apply product by sprinkling slowly over water surface in one application
- Circulate for 1 – 2 hours
- Always test and re-balance pH after application of Balance TA+
What is TA
- The total of all alkaline minerals in water
- Namely bicarbonates, carbonates, hydroxides
- The measure of waters ability to resist a change in pH
- Proper hot tub range: 125 – 150 ppm
- Acts as a buffer or shock absorber for pH
- Balance initially at fresh fill
- Check monthly and adjust as needed
Why Is It Important
- In hot tub water, a balanced total alkalinity does the following:
- Allows easier maintenance of pH within the desired range
- Helps protect surfaces from corrosion, staining and scale formation
- Helps provide clearer water
- Fewer problems / easier maintenance
Why Does TA Change
- TA is depleted in the buffering of acids and maintenance of proper pH
-
Product additions can have an effect on TA
- Bromine Tabs lower TA
- Balance pH- lowers TA
- Balance pH+ raises TA
- Aeration lowers TA
- Fill water can raise or lower TA
Problems Associated with TA
- When low – acidic
- pH bounces uncontrollably
- Corrodes surfaces
- Possible staining
- When high – scale forming
- High acid demand
- High pH
- Scale forms more readily
- Cloudy water (calcium)
