Similarly, we can consider whether our simple pool equipment is appropriate enough for the purpose of the pool: do we want to have a better water for our 10 min. swimming than we are having in our house water for our teeth brushing, cooking, dish washing, wife for sitting in bath tube, sometimes also for our drinking? Do the doctors in hospital get a better water (than my swimming pool) when they prepare themselves for a surgery?
Then, beside the investment cost - when we cannot persuade the wife for buying another diamond ring


I haven't studied the precious characteristics of the zeolite, just to the mentioning of "...though in fibrous form, they may have carcinogenic (cancer-causing) effects". Perhaps it is not so bad, similarly, as it was here once explained that the cyanuric acids that are added to the healthy chlorine are fully harmless. Anyway, I am not zeal enough to get a headache with much chemicals in my pool, I have got the water just for swimming.
