Effect of inconsistent beach trips and being lucky for having a swimming pool

The beach treatment is very effective but it needs to be done consistently (whenever there is signs of an infection). The level of infection decreases exponentially with each successive visit.

Unfortunately we were not able to revisit the beach but were fortunate that our swimming pool is quite acidic. There was a new outbreak but was a lot less contagious. In fact, the outbreak seemed so weak that it was not able, or very slowly able to increase. My daughter after swimming in our very acidic swimming pool cured herself of this infection and there has been non after that. However she has gone swimming more than once since that time. No new outbreaks and everything seems to be good.
