Each Element of Balanced Water

To maintain Crystal Clear water that is safe to swim in and feels gentle on your skin, balancing your water is absolutely crucial!
When balancing a Crystal Waters Pool, Spa or Swim Spa, it is advised to balance the water weekly, or when problems occur, before adding any other chemicals. If you’re not using a Crystal Waters chemical system, dosing recommendations will vary.
When talking about water balance, we’re talking about 3 different elements in your pool, spa or swim spa. These elements are Total Alkalinity, pH, and Calcium Hardness.
Each 3 elements work together in different ways to keep your water safe and sparkling!

Total Alkalinity

Total Alkalinity is used as a buffer to prevent changes in pH and must be balanced before any other element. If Total Alkalinity is too low, pH can fluctuate dramatically. If Total Alkalinity is too high, pH can lock at the high end of the scale which can cause water quality issues and an excessive amount of Crystal Waters pH Reducer or Crystal Waters pH Down will be needed to bring the pH back into the correct range. For spas or swim spas on a Crystal Waters System, we advice a Total Alkalinity of 120ppm – 150ppm. For pools using a Crystal Waters chemical system, we recommend a Total Alkalinity of 60ppm – 500ppm.
This is the optimum level to efficiently control the pH.

pH

pH is a measurement of hydrogen ions in water, presented as a scale. The neutral point in the scale is 7.0. This is the pH value of pure drinking water. In a controlled environment such as a pool, spa, or swim spa, the favourable pH value is between 7.2 – 7.8. If the pH becomes too low, it is considered acidic. Acidic water is soft and corrosive, and will cause damage to all the metals in your pool or spa such as pipes and jet faces. A pH that becomes too high is considered basic. Basic water has too many alkaline bases which means it can cause the calcium to come out of solution, giving scaly formations and cloudy water, and may also be higher in metals than neutral water, causing an odour, skin and eye irritation and occasionally chest irritation.
To maintain a safe pH level, balance Total Alkalinity first, to reduce the occurrence of drastic fluctuations. Once Total Alkalinity is in balance, pH must be balanced next and maintained at a level between 7.2 – 7.8. Check weekly.

Calcium Hardness

Calcium Hardness is a measurement of minerals such as calcium and magnesium in your pool, spa, or swim spa water. If there is not enough Calcium in your water and your water is too soft, the minerals will be drawn from other metals in your spa or pool causing corrosion of jets and pipes etc.
If your Calcium Hardness becomes too high, it can cause scaling formations, and cloudy water and an unpleasant chalky film and splash marks.
Calcium is the last element to be balanced, as an accurate reading on the Calcium level, isn’t possible until pH and Total Alkalinity are in the correct range.
If you’re on a Crystal Waters system, we recommend the Calcium reading to be 80ppm – 140ppm in spas and swim spas, and 80ppm – 500ppm in pools. Different chemical systems will have different requirements, in particular salt and magnesium based pools, as these can increase the calcium due to their similar properties.

Test Strips

To be able to accurately gage the levels of each element in your water, you will need Crystal Waters 4 in 1 Test Strips which can be ordered via our website.
Test Strips are simple to read! Just place the test strip in your pool, spa, or swim spa water for a few seconds, on a knifes edge angle. Remove from the water and compare the results to the back of the bottle after 10 seconds, for an accurate reading. Record the results you received and dose according to the Crystal Waters User Guide if using the Crystal Waters Pool and Spa Solutions chemical system, or the Manufacturer’s instructions for other systems. Ignore the bracketed areas on the test strip bottles.

Balancing Your Spa

To balance your spa the following products are needed:
-Crystal Waters Pool and Spa Solutions pH and Alkalinity Enhancer
-Crystal Waters Pool and Spa Solutions pH Reducer
-Crystal Waters Pool and Spa Solutions Calcium Enhancer.
Please note that pH and Alkalinity work together and will both rise and fall with the addition of Enhancer and Reducer.
Always balance Alkalinity first, pH second, and Calcium last.
Follow the Crystal Waters Spa User Guide and the Spa Balancing Cheat Sheet for further instructions.

Balancing your swim spa

To balance your swim spa the following products are needed:
-Crystal Waters Pool and Spa Solutions pH and Alkalinity Enhancer
-Crystal Waters Pool and Spa Solutions pH Down
-Crystal Waters Pool and Spa Solutions Hardness Increaser.
Please note that pH and Alkalinity work together and will both rise and fall with the addition of Enhancer and Down.
Always balance Alkalinity first, pH second, and Calcium last.
Follow the Crystal Waters Swim Spa User Guide and the Spa Balancing Cheat Sheet for further instructions.

Balancing your pool

To balance your swim spa the following products are needed:
-Crystal Waters Pool and Spa Solutions pH Buffer
-Crystal Waters Pool and Spa Solutions pH Down
-Crystal Waters Pool and Spa Solutions Hardness Increaser.
Please note that pH and Alkalinity work together and will both rise and fall with the addition of Buffer and Down.
Always balance Alkalinity first, pH second, and Calcium last.
