Frequently Asked Questions

How do I use 3-inch chlorine tabs in my pool?

3-inch chlorine tabs are typically placed in a floating dispenser (chlorinator), a skimmer basket, or an automatic inline/offline chlorinator. Do not place them directly on the pool surface or in the skimmer if your pool has a vinyl liner, as they can bleach or damage the liner. Do not put tabs in a skimmer basket if your pool has a heater as this can damage the heat exchanger.

How many chlorine tabs should I use for my pool size?

The number of tabs depends on your pool's volume, bather load, sunlight exposure, and current chlorine demand. Generally, one 3-inch tab treats about 5,000 to 10,000 gallons of water for a week. Always refer to the product label for precise dosing instructions based on your pool's size and desired chlorine levels.

How often should I add chlorine tabs to my pool?

Chlorine tabs dissolve slowly, releasing chlorine over several days. You should check your chlorine levels daily and replenish the tabs as needed, typically once every 5-7 days, to maintain a free chlorine residual of 1-3 ppm.

Can I put chlorine tabs directly into my pool skimmer?

While convenient, placing chlorine tabs directly in the skimmer can lead to highly chlorinated water sitting in your plumbing lines when the pump is off, which can corrode equipment over time. It's generally safer for equipment to use a floating dispenser or an automatic chlorinator. Avoid placing them in the skimmer for vinyl liner pools due to bleaching risk.

Why are my chlorine tabs dissolving too fast or too slow?

Too Fast: High water temperature, high bather load, heavy rainfall, or poor water balance (especially low cyanuric acid) can cause tabs to dissolve quickly.

Too Slow: Low water temperature, insufficient water circulation, or very high cyanuric acid levels can slow down dissolution.
