LEISURE TIME SPA
UP is used to raise the pH of spa and hot tub water. It is important to maintain the pH
between 7.2 and 7.8. The pH is effectively maintained by keeping total alkalinity between
80 ppm (Parts Per Million) and 140 ppm. pH and total alkalinity are related. Low
alkalinity should be raised prior to adjusting pH. Use chart below for doasges, all
measurements are dry ounces. Wait atleast 24 hours between adjustment and retesting.
ACTIVE INGREDIENT: Sodium Bicarbonate … 100%
TOTAL ALKALINITY:
Total alkalinity is the amount of "buffer" in the water (fourd in the form of carbonates and biocarbonates). These buffers do just that they buffer drastic change in pH, called "pH bounce." We recommend that you keep you alakinity between 80 to 120 ppm. Most water supplies are with in this range which means you shouldn't have to adjust this often if your changing your spa water every 3 to 4 months as reccomended.
Testing your alakalinty can be done with most test strips or 4 in 1 test kits. Do to the buffering effect that alkalinity has on pH it is our reccomendation that you always make sure it is in the range of 80 to 120 ppm before adjusting your pH. If you find that your alkalinity is out of range you can use the following charts to adjust your alkalinity.
TO RAISE YOUR ALAKALINITY |
||||
| Desire Amount of Raise | Spa Volume (gallons) |
|||
| 200 | 300 | 400 | 500 | |
| 20 ppm | 1 | 1-1/2 | 2 | 2-1/2 |
| 40 ppm | 2 | 3 | 4 | 5 |
| 60 ppm | 3 | 4-1/2 | 6 | 7-1/2 |
| 80 ppm | 4 | 6 | 8 | 10 |
| 100 ppm | Any time your alkalinity is off by 80 ppm or greater it is recommended that you drain and start with fresh water | |||
pH:
pH has one of the greatest effects on water balance. pH is a measure of how acidic or basic it is measured on a scale from 0 to 14. At 7.0 pH is neutral, anything below that is acidic and can lead to damage to equipment and the spa surface. pH abve 7.0 is basic. While spas run slighlty in the basic range of 7.2 to 7.8 a pH higher than 7.8 can cause minerals to "drop" out of solution leaving deposits on the equipement and the spa surface.
Testing your pH can be done with almost all test strips and test kits. After testing your pH if you are not in the range of 7.2 to 7.8 and your alkalinity is correct use the following tables to adjust you pH.
TO RAISE YOUR pH |
||||
| To Raise pH from: | Spa Volume (gallons) |
|||
| 200 | 300 | 400 | 500 | |
| below 6.8 | 1/2 | 5/8 | 3/4 | 1 |
| 6.8 -7.0 | 1/4 | 3/8 | 1/2 | 5/8 |
IMPORTANT:
Always turn blowers off prior to adding any chemical. When increasing or decreasing total alkalinity never make an adjustment any greater than 40ppm in a 24 hour period
