GLB Alkalinity Up 10lb – Pool Water Balancer
Balance Your Pool for Cleaner, More Comfortable Water
Clear, sparkling water starts with balanced chemistry—and one of the most overlooked but critical factors is total alkalinity. When alkalinity levels drop too low, pH becomes unstable. This makes chlorine less effective. Swimmers may then have eye or skin irritation. The solution? GLB Alkalinity Up 10lb.
This easy-to-use balancer raises total alkalinity quickly and safely, stabilizing pH and preventing wild fluctuations that make pool care frustrating. Whether you are a first-time pool owner or an expert, Alkalinity Up is essential. It helps keep your pool water clean, comfortable, and easy to care for.
Why Alkalinity Matters in Pool Care
Total alkalinity acts as a “buffer” for pH. Without proper alkalinity levels, even small additions of chemicals can cause large swings in pH balance. This leads to a chain reaction of problems:
-
Cloudy water and increased scaling risk
-
Metal corrosion in heaters, pumps, and ladders
-
Reduced chlorine effectiveness, meaning more sanitizer is wasted
-
Skin and eye irritation for swimmers
By maintaining the right alkalinity (typically 80–120 ppm), you create a stable foundation for balanced, healthy pool water. GLB Alkalinity Up makes this process simple and reliable.

How It Works
GLB Alkalinity Up is made from sodium bicarbonate, a safe and effective compound used to increase total alkalinity. When added to pool water, it raises alkalinity into the proper range, preventing pH drift and protecting water balance.
Because it works gradually and predictably, Alkalinity Up won’t overshoot levels when applied correctly, making it one of the most user-friendly chemicals in pool care.
When to Use Alkalinity Up
-
At Pool Opening – Fresh fills often have low alkalinity, requiring adjustment.
-
After Heavy Rain – Rainwater dilutes pool chemistry, lowering alkalinity.
-
With Frequent Swimmer Load – Sweat, oils, and bather waste impact chemical stability.
-
When pH Fluctuates Wildly – If you’re constantly adding pH up/down, low alkalinity is often the cause.
-
As Routine Maintenance – Regular testing ensures your pool stays within the 80–120 ppm range.
Application & Directions
-
Test Water First – Use a test kit or strips to measure current alkalinity.
-
Calculate Dosage – Follow GLB’s label for exact ounces per 10,000 gallons needed.
-
Add Directly to Pool – Broadcast evenly across the deep end with the pump running.
-
Allow to Circulate – Run circulation for at least 2–4 hours.
-
Retest & Adjust – Recheck levels the next day and repeat if necessary.
⚠️ Important: Never add Alkalinity Up at the same time as other balancing chemicals. Space applications several hours apart.
