Ice Bath Calcium Hardness Increaser - by Clear as Ice - LoChlor

Coming Soon!

Clear as Ice Hardness Increaser

Clear as Ice Hardness Increaser raises calcium hardness to protect your ice bath surface and equipment against the corrosion caused by soft, mineral-hungry water.

Directions

Add 10g per 1000 litres to increase hardness by 10ppm. To reduce hardness, dilute by draining some water and topping up with fresh water. Run filtration for 30 minutes before re-testing.

Important Points to Note

Clear as Ice by Lo-Chlor uses a non-chlorine sanitiser and is not compatible with chlorine. Because tap water can contain chlorine, Clear as Ice Chlorine Remover must be added whenever you first fill or top up your ice bath.

• Always run filtration when adding any chemical, and wait 30 minutes between each adjustment.
• Always adjust Total Alkalinity before pH.
• Know exactly how many litres of water your ice bath holds — accurate volume is essential for correct dosing.
• Test your water at least weekly (more often with heavy use) and adjust as per the guide below.
• Run filtration daily.

Start-Up & Maintenance Guide

Always run filtration while adding chemicals and wait 30 minutes between each adjustment. Alkalinity Increaser raises both Total Alkalinity and pH, so always adjust TA first. Know how many litres your bath holds before you start.

Initial Start-Up

Fill the ice bath and start filtration. Add 12.5ml Clear as Ice Chlorine Remover per 1000 litres and run filtration for 30 minutes. Use test strips to check and adjust your water balance as per this guide.

Adjusting Total Alkalinity (TA)

Ideal range 80–120ppm. To raise TA by 10ppm, add 18g Clear as Ice Alkalinity Increaser per 1000 litres and run filtration for 30 minutes. Do not add more than 40g per 1000 litres at a time; wait 30 minutes before re-testing.

Adjusting pH & Calcium Hardness

Once TA is correct, check pH (ideal 7.2–7.6) and calcium hardness. To lower pH by 1 unit, add 43g Clear as Ice pH Reducer per 1000 litres. To raise pH by 1 unit, add 18g Clear as Ice Alkalinity Increaser per 1000 litres. To raise calcium hardness by 10ppm, add 10g Clear as Ice Hardness Increaser per 1000 litres. Run filtration for 30 minutes between adjustments and measurements.

Testing Your Water

Clear as Ice is designed to be used with AquaSpa Insta-Test Strips. Test at least weekly and adjust to the guide above. As used by SpaPro and others.
