How to use

HTH® Chlorine Granules Ultra

1. Measure Correct Dosage

Follow the on-pack instructions according to the size of your pool. Make sure to use a clean, dry scoop.

2. Apply Directly To Pool Water

While the filter pump is running during the evening, apply chlorine granules evenly over a wide area in the deepest part of the pool. Use a brush to disperse any granules that fall to the bottom of the pool.

3. Test Free Available Chlorine (FAC)

After granules have dissolved completely, use HTH® 6-Way Test Strips to test FAC. Do not enter your pool until the free available chlorine residual is 1 to 4 ppm (parts per million).

Great Color
Size: 1 Count (Pack of 1), Style: Cartridge Ink
I was hesitant on purchasing this item. My skepticism was relieved when I installed and printed the first picture...very good quality. However, seems like the ink supply went quickly, either not a complete cartridge or I print too much(which I don't).

Good quality
Size: 1 Count (Pack of 1), Style: Cartridge Ink
I would say great value, but I can buy it for the same price in store. I think it’s more of convenience to be able to get it without having to go out.
