The short answer
Chlorine can kill many pool germs, but Cryptosporidium is unusually tolerant of standard pool chlorine levels. That is why pool operators use special hyperchlorination procedures when Crypto contamination is suspected.
Why Crypto matters
Cryptosporidium, often called Crypto, is a microscopic parasite that can cause stomach illness. In pools, the concern is that it can spread through contaminated water even when a pool looks clear and chlorine levels appear well maintained.
What this means for pool owners
Good pool care is still essential: healthy circulation, clean filtration, balanced water, and safe swimming habits all matter. Nobody should swim while sick with diarrhea, and swimmers should avoid swallowing pool water.
Where Aquastaser fits
Aquastaser is not a public-health emergency treatment for Crypto exposure. It is a chlorine-free pool system for owners who want a different day-to-day water-care routine and fewer harsh chemical steps around the pool.
Questions to ask before changing systems
Before replacing a chlorine or saltwater routine, look at your pool size, plumbing, pump flow, filtration, and current water condition. If you are unsure, ask Aquastaser support before ordering so the system is matched to the pool you actually own.
