GLB 4Ib pH Down |
$15.10 |
|
|
|
Lowers pH level in swimming pool water.
When pH Value Rises Above 7.8: While the pump is in operation, distribute 4 oz. (1/4 lb.) for each 10,000 gallons of water into the deep end of the pool (but not near metal fittings or the skimmer).

|
GLB 4Ib pH Up |
$14.99 |
|
|
|
Increases the pH level in swimming pool water. When pH Falls Below 7.2: While the pump is in operation distribute pH UP into the deep end of the pool.
|
|
GLB 6Ib Calcium Hardness Up |
$17.99 |
|
|
|
Increases water hardness to prevent foaming, equipment corrosion and scaling.
Normal:
1. Determine calcium hardness level. It should be between 150-250 ppm.
2. If the level is below 150 ppm, add CALCIUM HARDNESS UP by distributing the product over the water surface. 1 lb. of CALCIUM HARDNESS UP will increase the calcium hardness 10 ppm in 10,000 gallons of water.

|
GLB 7.5Ib Alkalinity Up |
$17.99 |
|
|
|
Increases Total Alkalinity in swimming pool water. Maintaining proper alkalinity in swimming pool water aids in preventing the pH level from changing. To Increase Total Alkalinity:
1. Determine the total alkalinity level.
2. If the value is below 75 ppm, add a sufficient amount of ALKALINITY UP - by pouring it directly into the pool - to increase the total alkalinity to at least 75 ppm.
ALKALINITY UP will provide approximately 10 ppm increase in total alkalinity for each 10,000 gallons of water. Wait at least 8 hours for the material to distribute uniformly before rechecking the alkalinity level.
