Frequently Asked Questions
Q: How often should I use this product?
A: Add tablets as needed to maintain 1–4 ppm free chlorine, based on pool size and usage.
Q: Can I use this in saltwater pools?
A: Yes, but only when supplemental chlorine is needed — monitor water balance closely.
Q: What’s the shelf life?
A: When stored in a cool, dry place, these tablets remain effective for up to 2 years.
Q: What makes Cal Hypo tablets different from Trichlor tablets?
A: Cal Hypo tablets sanitize without adding cyanuric acid (CYA), which prevents chlorine lock. Trichlor tablets contain CYA, which can build up and reduce chlorine effectiveness over time.
Q: Can I use these tablets with my automatic chlorinator?
A: Only if the chlorinator is specifically designed for Cal Hypo tablets, like the Poolife™ NST Feeder. Do not use them in feeders meant for Trichlor tablets, as they may cause a reaction.
Q: How many tablets should I add at a time?
A: The number depends on pool size, temperature and bather load. Always test water first and adjust to maintain 1–4 ppm free chlorine. Start with fewer tablets and increase as needed.
Q: Can I mix these tablets with other types of chlorine?
A: No. Never mix Cal Hypo with Trichlor or Dichlor tablets in the same feeder, skimmer or floater. Doing so may cause a dangerous chemical reaction.
