Spa TA Plus 1Kg

AquaSparkle Spa TA Plus is a measurement of the waters ability to resist pH change. If the total alkalinity is low then the pH can fluctuate making it difficult to control and maintain at the ideal level. If the total alkalinity is high then the pH can be difficult to change and will keep rising.

A high total alkalinity can also lead to the formation of a bicarbonate scale on spa surfaces,
within pipework and support equipment.

If the total alkalinity of your spa water is below 80mg/l it should be increased using AquaSparkle Spa T.A. Plus, the table below indicates the dosage quantities required:

AquaSparkle Spa TA Plus Dose Rates:
To Increase TA in 1,000 Litres by 10mg/l requires 18g of TA Plus
To Increase TA in 1,000 Litres by 25mg/l requires 45g of TA Plus
To Increase TA in 1,000 Litres by 50mg/l requires 90g of TA Plus

If the total alkalinity of your spa water is above 150mg/l then AquaSPArkle Spa pH Minus can be used to lower it. When applying Spa pH Minus to lower total alkalinity levels, the product should be predissolved and then ‘slug’ dosed (dumped) into one area of the spa.
