About this item
Product details
Low alkalinity levels in swimming pool water can cause undue damage to pool surfaces and equipment. HTH® Pool Care Alkalinity Up not only raises the total alkalinity in your pool water, but it also helps keep the pH levels from fluctuating. This helps prolong the life of pool surfaces and equipment, like filter systems, and ensures healthy, comfortable swimming water by protecting against skin and eye irritation. HTH® Pool Care Alkalinity Up is great for all pool types, including vinyl-lined pools and salt water systems.
How to Use HTH® Alkalinity Up Use HTH® 6-Way Test Strips or Test Kit to test your water weekly and make sure the total alkalinity level is between 60 and 120 ppm. If alkalinity is below 60, add HTH® Alkalinity Up directly to the pool water to raise the alkalinity level and help keep pH levels in range.
- Raises total alkalinity levels in pool water.
- Helps pH levels from fluctuating.
- Protects equipment and pool surfaces.
- Raises alkalinity levels.
- Keeps total alkalinity and pH levels in range in swimming pool water.

Works as it should
We got hth pool strips that we dunk and take a picture of and it'll tell us where our levels sit and if we need to bring any levels up. If they aren't where they need to be it'll give us suggestions for what we need and how much. This was purchased because of that and works great.
This is perfect!!!
[This review was collected as part of a promotion.] I absolutely love the purity of this product. I am always looking for the purest option for me and my family, and this is 100% only ONE ingredient, and it's natural!!! This is part of a system to treat pools, and it raises the alkalinity of the water. This product is number one in the system, and I'd highly recommend this over other products with synthetic chemicals, because this has none. The instructions are right on the big bottle,and clear and easy to follow, and it even has instructions for what else to buy to make your pool healthy,including a "test to swim" app, to ensure safety! This makes me see how this company wants safety for my family just as much as me! I'd recommend this product highly!!!!
