There are two types of Chlorine used in swimming pools, stabilised and un stabilised. The un-stabilised is liquid chlorine that is available normally in a bottle and the other which is stabilised chlorine that is in tablet form like a dishwasher tablet that contains CYA.
Liquid chlorine can be harmful if not handled in the correct manner and is a toxic substance. It has been used for many years in the swimming pool industry and still is today. People do need to move away from this chemical that is not only harmful to the public but also the environment.

A salt water swimming pool has been marketed as a alternative to a chlorine. You don’t add chlorine but the chlorinator converts the salt into chlorine. It just means that the pool has less added instantly to the pool as it has to go through the chlorinator. The only main benefit is that a salt water chlorinator does not have the same intense chemical smell as a chlorinated swimming pool. Chlorine over the past decade has been proven to be the most harmful form of swimming pool sanitisation. PLUS POINT: Very affordable.

A UV system basically neutralises bacteria in the water so it can’t reproduce. The UV system only can nautralise bacteria that flow through the UV rays so the water is constantly being pumped through as bacteria and algae are not being attacked by latent ions which are produced when using a Quest System.. The UV systems don’t oxidize the water only ionise it. 

The copper ions attack the outer membrane of the algae cell by attaching to it , this causes the outer cell to leak and die.  The silver ions that are produced in the electrolysis attack any bacteria that are present in the pool water and filtration system. The silver is also more effective than many chemicals in killing bacteria, especially biofilm which chlorine cannot kill. This is a very effective way of killing algae but on it’s own does not give enough protection. It needs a secondary sanitiser such as a salt water chlorinator or an electronic oxidiser.

Traditionally Copper and Silver ionisation systems have required an oxidiser to be added to the pool water to help burn out organic compounds (oils, dust, leave stains etc.). The most common form of oxidiser used for this purpose has been chlorine.

Electronic oxidisation is when an atom or ion loses one or more of its electrons to a chemical reaction.

The oxidiser attacks the phosphates, such as sun cream lotion , dust and other organic compounds in the pool by targeting their outer cells and taking an electron rendering inactive and eradicating it. Using just an Oxidiser is not enough to completely sanitise a swimming pool. You still need to break down the algae , most people again use an algaecide and other chemicals.

Ozone is a good oxidiser that unfortunately has a very short efficacy due to its short life. You have to purchase an Ozanator which are very expensive which works by injecting the Ozone gas into it which in turn flows to the pool. It does require a residual sanitiser that is commonly Chlorine. Ozone is extremely toxic and the Ozanator are expensive to maintain and run. The pump needs to be on constantly to circulate the Ozone , so is a costly alternative.
