Description

Genuine Acti Spa Alkalinity Increaser 1KG

Genuine Acti Spa Alkalinity Increaser 1KG is an essential water treatment chemical designed to raise and stabilise total alkalinity levels in hot tubs and spas. Maintaining the correct alkalinity balance is crucial for stable water chemistry, comfortable bathing conditions, and long-term protection of spa equipment.

Low total alkalinity can cause unstable pH levels, leading to water that becomes corrosive, uncomfortable for bathers, and damaging to pumps, heaters, and other spa components. Genuine Acti Spa Alkalinity Increaser 1KG helps restore proper alkalinity balance, allowing pH levels to remain stable and ensuring your spa water stays clean, safe, and easy to maintain.

By regularly testing and adjusting alkalinity levels using Genuine Acti Spa Alkalinity Increaser 1KG, you can maintain a balanced spa environment, improve water stability, and protect your spa system from unnecessary wear.

Key Features

Raises Total Alkalinity

Genuine Acti Spa Alkalinity Increaser 1KG is specifically formulated to increase total alkalinity levels in spa and hot tub water. Proper alkalinity helps maintain balanced water chemistry and prevents rapid pH fluctuations.

Stabilises pH Levels

When total alkalinity is too low, pH levels can swing unpredictably. Genuine Acti Spa Alkalinity Increaser 1KG helps stabilise pH, making ongoing water maintenance easier and more reliable.

Prevents Corrosion

Low alkalinity water can become corrosive and may damage heaters, pumps, seals, pipework, and spa surfaces. Maintaining correct alkalinity levels helps protect spa equipment and extend its lifespan.

Maintains Ideal Water Balance

Regular use of Genuine Acti Spa Alkalinity Increaser 1KG helps keep your spa water within the recommended alkalinity range, promoting comfortable bathing conditions and consistent sanitiser performance.

Recommended Total Alkalinity Range

For spas and hot tubs, the recommended total alkalinity (TA) level is:

80 – 150 mg/l (ppm)

Maintaining alkalinity within this range helps prevent pH instability and ensures effective water treatment.

If alkalinity falls below this range, Genuine Acti Spa Alkalinity Increaser 1KG should be used to restore proper balance.

Dose Rates

Water Volume	To Increase Total Alkalinity by 10 mg/l (ppm)	To Increase Total Alkalinity by 25 mg/l (ppm)
1,000 Litres (220 Gallons)	18g	45g
1,500 Litres (330 Gallons)	27g	68g

Always test the water before dosing and adjust gradually if required.

Directions for Use

Test the Water

Begin by testing the total alkalinity of your spa or hot tub water using a reliable test kit. If the level is below 80 mg/l, treatment with Genuine Acti Spa Alkalinity Increaser 1KG is recommended.

Pre-Dissolve the Product

Measure the required amount according to the dosing chart. Dissolve the granules in a clean plastic container using 1 litre of warm water for every 10g of product, stirring until fully dissolved.

Add to the Spa

With the spa circulation system running, slowly pour the dissolved solution near the water inlets to allow for even distribution throughout the spa.

Circulate the Water

Allow the spa pump to circulate the water for at least 30 minutes to ensure the product is fully mixed.

Re-Test the Water

After circulation, test the alkalinity again and repeat the process if necessary until the recommended range is reached.
