Product description

Product description Alkalinity Increaser raises the Total Alkalinity reading and prevents fluctuations during pH adjustment. Alkalinity readings should be maintained between 80 150ppm. Instructions 1. Check the water on a weekly basis with a quality test kit and ensure the Total Alkalinity reading is above 80ppm. 2. If the reading is below 80ppm and to raise the Total Alkalinity reading in 10ppm increments, add 30g of Spa Alkalinity Increaser per 1000lts of water and add directly to the water (with circulation running). 3. Re-test the water to ensure you have attained the desired reading. 4. Only add Spa Alkalinity Increaser in stages and always re-test after additions. 5. If you experience difficulties with the water please contact your local dealer. PRECAUTIONS Always ensure bathers are out of the water when adding chemicals. Never mix with any other chemicals including cleaning products, weed killers and chlorine products, as a dangerous reaction may occur. Always handle products in a well-ventilated area. Always wash hands thoroughly after handling chemicals. Store in a cool, dry, well ventilated, secure place. Ensure chemicals do not become damp in storage. Instructions and dosages given are a guide to most effective use. WARNING This container must not be used or contaminated with any other materials. Directions 1. Check the water on a weekly basis with a quality test kit and ensure the Total Alkalinity reading is above 80ppm. 2. If the reading is below 80ppm and to raise the Total Alkalinity reading in 10ppm increments, add 30g of Spa Alkalinity Increaser per 1000lts of water and add directly to the water (with circulation running). 3. Re-test the water to ensure you have attained the desired reading. 4. Only add Spa Alkalinity Increaser in stages and always re-test after additions.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
