Frequently Asked Questions

Q: How often should I add chlorine tablets?
A:
Check and adjust weekly, adding tablets as needed to maintain 1-4 ppm free chlorine.

Q: Can I use these tablets in saltwater pools?
A:
Yes, but monitor cyanuric acid levels as they can build up over time.

Q: What’s the shelf life of pool chlorine tablets?
A:
When stored properly in a cool, dry place, tablets maintain effectiveness for 2-3 years.

Q: Can I break the tablets to fit smaller feeders or floaters?
A: No. Do not break or crush the tablets — this can release chlorine too quickly and may damage surfaces or equipment. Use a feeder or dispenser sized appropriately for 3-inch tablets.

Q: What’s the difference between these tablets and regular chlorine tablets?
A: Poolife™ MPT Extra™ tablets are multi-functional — they sanitize, prevent algae, clarify water and protect against stains and scale, eliminating the need for multiple separate products.

Q: Can I use these tablets during heavy swimmer load or heat waves?
A: Yes. Just be sure to test chlorine levels more frequently during high usage or hot weather, as chlorine may be consumed more quickly.

Q: Should I still shock my pool if I use these tablets?
A: Yes. While these tablets provide ongoing sanitization, weekly or bi-weekly shock treatments are still recommended to oxidize contaminants and maintain water clarity.
