Water Balance : Keeping your water balance in balance
Maintaining your pool water in the proper balance pays big rewards. First, water that has its key chemical factors in the appropriate balance range makes for very comfortable swimming. Second, balanced water makes pools easier to maintain. Properly balanced swimming pool water meets the following criteria:

  • pH: 7.2-7.8.
  • Metals: none
  • Total Alkalinity: 80-150 ppm.
  • Calcium Hardness: 180-250 ppm (vinyl pools). 200-275 ppm (plaster pools).
  • Total Dissolved Solids: less than 1,500 ppm.Your Authorized BAQUACIL Dealer carries the full range of BAQUACIL BALANCE CHEMICALS, specially designed to make water balance adjustments quick and easy.

As with all pool chemicals, make sure to follow the instructions and precautions on the labels of all BAQUACIL BALANCE CHEMICALS products.
Use your BAQUACIL TEST STRIPS to check your water’s pH and alkalinity once a week, or after any major change (such as when you add a large amount of new water, or after a long, heavy rain). Take a water sample to your Authorized BAQUACIL Dealer each month for a full water analysis.

Total Alkalinity Control
The amount of alkalinity in your water can affect swimmers’ comfort. High alkalinity will push the pH reading upward, while low alkalinity can promote pool corrosion and cause "pH bounce," which is a large change in the pH reading after you add adjustment chemicals. The ideal total alkalinity range is 80-150 ppm. Always test and adjust the total alkalinity level before adjusting the pH.

pH Control
pH is a measure of the acidity or basicity of the water and is measured on a scale ranging from 0-14. Swimming pool water should have just a little basicity with a pH reading between 7.2 and 7.8.
If pool water is too basic, scale can develop — particularly in hard water areas. If it is too acidic, the water can become corrosive.

Calcium Hardness Control
Calcium Hardness also affects the balance of your pool water. Low Calcium Hardness will promote corrosion. High Calcium Hardness can cause cloudiness and scaling. The ideal Calcium Hardness content is 200-275 ppm for plaster pools, and 180-250 ppm for all other types.
Take a water sample to your Authorized BAQUACIL Dealer if you have a Calcium Hardness problem.

Metals
It is not uncommon to find metals, often called free metals, dissolved in pool water. Usually they come from source water, sometimes they come as a result of the erosion of metal pool fixtures, such as heater cores.
Free metals in pool water can cause staining of pool surfaces and inhibit the performance of water sanitizers. Ideally, there should be no metals in the water: 0 ppm.
Your Authorized BAQUACIL Dealer can determine the presence of free metals in your water. If metals are detected, BAQUACIL METAL CONTROL can be used to “sequester” them, rendering them harmless.
