FAQ's regarding this product...

Does chlorine make your eyes sting ? 
No, having an incorrect pH level causes eye sting and skin irritation.

Can I sprinkle the granules directly into my spa water ? 
Yes as the water is warm and a spa has a smaller volume than a pool the granules will dissolve when applied directly to the spa water.  Simply turn your spa pumps on, sprinkle in and let it circulate to dissolve evenly.  However with pools we recommend you pre-dissolve in a clean plastic bucket filled with pool water.

Will this chlorine damage my spa cover ? 
No, but you should ensure your spa cover is left off for 10 mins after dosing to prevent any deterioration.

How do I measure the amount of chlorine in my spa ? 
By using chlorine test strips. Our range of chlorine test strips can be viewed by clicking here.
