The general guideline for adding chlorine tablets to a pool is:
- Use one 3-inch chlorine tablet per 5,000 gallons of pool water. For example, a 10,000-gallon pool would need two 3-inch tablets
- Another common recommendation is two 3-inch tablets per 10,000 gallons, which is equivalent to one tablet per 5,000 gallons
- Some sources suggest one 200g (3-inch) tablet per 20,000 liters (about 5,000 gallons) per week as a maintenance dose
- Tablets typically dissolve slowly over 3-5 days, so adding tablets once or twice a week helps maintain a chlorine level of 1-3 ppm, which is ideal for pool sanitation
For smaller pools, 1-inch tablets are used, with roughly one tablet per 300 gallons
. It is important to test your pool's chlorine level regularly and adjust the number of tablets accordingly to maintain the proper chlorine concentration. Avoid putting tablets directly into the pool water to prevent damage to surfaces; instead, use a skimmer or a floating dispenser
. Summary:
Pool Size (gallons)| Number of 3-inch Tablets (per week)
---|---
5,000| 1
10,000| 2
15,000| 3
20,000| 4
30,000| 6
Adjust based on pool usage, weather (sunlight depletes chlorine), and chlorine test results
