Following on from the previous thread.
Regeneration of Zeolite is normally done at the Beginning of EACH season. WHY?
Because it’s done to maximise the benefits of the UNIQUE quality of Zeolites and that is Ion/Canton Exchange, which means that this material has a capacity to 'absorb' Ammonia (NH4) along with a number of other unwanted compounds and metals in your pool water. For your wider comprehension, Ammonia will be produced in the process of Oxidisation of organic matter in the water from chlorination. Ammonia aids and amplifies the IsoChloramines which is the by-product responsible for the nasty smell and taste of pool water (often mistaken for chlorine).
So once the season is ready to start if you dose your filter with the right number of Kgs of Rock Salt (quantity depends on volume of the filter) and let it soak for 48 hours then a strange thing happens, meaning that the Sodium atoms in the Salt (NaCL) displace the Nitrogen in the Ammonia which is trapped in the Zeolite and therefor liberate the space so that the Zeolite can go on absorbing Ammonia for another year.... MAGIC! Cleaner water and a nicer pool for another year... all because of a gift from nature.... Mineral Zeolite!
So your job is to keep it at its best and that means - regeneration using rock salt.
