Sanitiser	Economy	Ease of Use	Advantages	Disadvantages
Ozone	Approx £130 every 2 years	Automatically operates during normal spa filtration	Reduces the required amount of bromine or chlorine Most new spas come with ozone already fitted.	Needs to be supplemented with chlorine or bromine Can be expensive...£120 depending on the application Bulb or chip needs replacing every 2 years
Chlorine Granules	Approx £60 per year	Top up with granules every 1 -3 days.	Very powerful sanitiser/shock. Relatively inexpensive More neutral pH...sodium di-chlor has a pH of 7.0 Readily available...Most Pool and Spa dealers carry it. Less expensive than bromine Can be used as sanitiser and also as "shock" Can be used with ozone and Nature2	The smell of water, skin, and bathing costume People complain of dry skin after spa use Once free chlorine has been combined with waste the resultant chloramines are poor sanitisers Requires frequent testing and adjustments Less convenient...needs to be added manually several times a week Numerous types are available, only sodium di-chlor should be used in spas Combined chlorines cause the "odour" but have no sanitizing ability
Chlorine Tablets	Approx £60 per year	Added less frequently than granules. Floats in a dispenser slowly dosing the pool for up to 10 days	Very powerful sanitiser/shock Relatively inexpensive More neutral pH...sodium di-chlor has a pH of 7.0 Readily available...Most Pool and Spa dealers carry it	Smell People complain of dry skin after spa use Once free chlorine has been combined with waste the resultant chloramines are poor sanitisers Can be sometimes difficult to maintain chlorine levels after a heavy bather load or after a refill
Bromine Tablets	Approx £80 per year	Top up with granules every 1 -3 days	Convenient to use... put tablets into a floater and refill every 10 to 14 days Readily available...most pool and spa dealers carry it Can be used with ozone Does not have "a chlorine smell" No difference between the effectiveness of free vs. combined bromine	Unlike chlorine, once bromine combines with waste, bromamines are still an effective sanitiser Degrades in direct sunlight May fade jewellery Requires frequent testing and adjustments Has low pH (approx. 3.5 - 4.5)...pH levels need to be adjusted frequently to prevent equipment damage More expensive than chlorine Can not be used with Nature2 Bromine odour is more difficult to shower off Requires the use of 'sodium bromide' when water is changed to establish a bromine reserve
Aquafinesse	Approx £240 per year	Once a week application of the Aquafinesse liquid. We also recommend a once week non-chlorine shock application	Easy and convenient to use Subtle lavender smell to the water The water feels less heavy and greasy We have very few problems when people convert to Aquafinesse from traditional maintenance programmes	We will need to use a anti-scale in areas of hard water, otherwise, a powdery scale may form on the shell Very expensive Often miss-sold as chlorine-free, a small chlorine tablet is used with the system, though the chlorine levels are not usually noticeable
Active Oxygen	Approx £70 per year	Once a week application of activator liquid. application of fast dissolving tablets every time you use the spa	No harsh smells Very good for people with sensitive skin. (used in birthing pools) relatively inexpensive Can be used in conjunction with chlorine as an occasional shock
Silver Mineral			Will dry/irritate the skin, cause eye redness, or fade bathing suites Will not degrade spa cover vinyl Uses copper and silver for sanitizing...similar to the space shuttle No chemical odours Can be used in indoor spas Has no effect on pH levels	Copper and Silver rods need to be replaced every year or two Very expensive Kills organic matter, but doesn't oxidize them Spa still needs to be chemically shocked occasionally
Spa frog			Easy to use...fits in filter Lasts 4 months Can be used with chlorine or ozone No chemical smells	Need to shock frequently with chlorine or non-chlorine shock
