Australian Spa Parts - Bioguard Spa Chemicals - Spa Water Chemistry


ALL spas require chemicals to treat the water. Correctly maintaining water chemistry is essential to equipment longevity AND user health

We stock a range of Bioguard and Bond spa specific chemicals to ensure you have everything required to look after your expensive investment as well as protect you and your family against bacteria and other undesireable health issues that can manifest in poorly maintained spas

Recommended ranges
Liquid Lithium Chlorine 1-3ppm
Armour Dichlor/Bromine 3-5ppm
pH  7.4-7.6
Total Alkalinity  80-120ppm
Calcium Hardness  150-400ppm

Reading outside of these ranges
When lower - generally results in corrosion, staining, foam, uncontrollable pH
When higher - generally results in scaling, cloudy water, hard to correct pH

Clarifier - only use with pleated filter cartridges
If you spa is fitted with fine micron bags or depth polyspun filters, they will be prematurely ruined when used with clarifier. A low micron filter is effectively the clarifier.

Bromine - there are 2 types of bromine. Tablet and granular
Tablet bromine has been available for many years and commonly used - they are often 'set and forget' resulting in less than required testing and correcting. Huge failure rates of spa equipment are experienced when tablet bromine is used. Particularly heaters.
We do NOT endorse the use of bromine tablets.
On the other hand in Australia, granular bromine is relatively new. Its manufactured very differently and is in fact majority Dichlor with a small percentage of bromine. Because its granular, it needs to be added more frequently in small dose rates, typically in conjunction with water testing. When used as instructed, minimal changes to pH and alkalinity occur and therefore less corrosive damage to spa equipment.

Introduction of chemicals into the spa
ALL chemicals should be broadcast into the body of water of the spa with filtration equipment running. There is no need to dissolve in a bucket of water first.
NEVER introduce spa or pool chemicals in proximity or directly into the skimmer - high concentration of these chemicals will damage heaters, seals and other parts. If you insist on using bromine tablets do NOT position them in the skimmer basket or a free floating dispenser. Always tie a floating dispenser so it cannot rest against the skimmer when filtration is running.

Ensure you have a quality test kit. You should test spa water at least 1-2 times per week. Make your chemical adjustments and test again to confirm each test is now within the correct range. If not, repeat the procedure until it is. Do NOT rely on monthly shop tests. Untold irreversible damage can be done in this timeframe. Shop tests should be regarded as a back up only to your own regular testing.
