The difference between HOCl and OCl- is the speed at which they oxidize. Hypochlorous acid is able to oxidize the organisms in several seconds, while the hypochlorite ion may take up to 30 minutes.
Pool & Spa Tips - Salt Chlorination
Is there a difference between ‘salt chlorinator’ chlorine and ‘normal’ chlorine?
A salt chlorinator makes chlorine the same way a chlorine factory does. The difference is that it is manufactured in your pool. Liquid chlorine is approximately 12.5% pure, whereas Electrochlor’s chlorine is 100% pure.
Will I ever need to add standard pool chlorine again?
From time to time it may become necessary to add some chlorine to the pool. This may be due to heavy rain or if the chlorine level needs to be shocked back up.
Does the salt damage pool equipment?
No. Low levels of salt have relatively insignificant corrosive effects on pool fittings and equipment.
How do I get started?
It’s easy! After installing your salt chlorinator, you simply add the recommended amount of salt to your pool and choose your desired chlorine level.
How much salt will I need?
1 kg of salt in 1,000 litres of water raises the salt level by 1,000ppm. Therefore, 420 kg of salt will raise a 70,000 litres pool from 0 ppm to 6,000 ppm.
What type of salt should I use?
High purity salt, it is important that the salt does not contain additives. Any common salt (like table salt) usually has an additive that may have staining properties.
