Water Testing and Analysis
Test the water in your pool two to three times a week. Do this to ensure an optimum swim environment and a long life for your pool. For the best sample of water, collect from the deep end of the pool – collecting at least eight ounces of water. You can collect the water in a sample bottle or any clean, plastic container.
Water Testing Ranges
|pH||7.2 – 7.6|
|Total Alkalinity||120-150 parts per million|
|Calcium Hardness||200-250 parts per million (Concrete Pools)|
|Calcium Hardness||175-225 parts per million (Vinyl Pools)|
|Free Chlorine||1-3 parts per million|
|Free Bromine||3-5 parts per million|
|Metals: Copper||0 parts per million|
|Metals: Iron||0 parts per million|
The most important factor to your water balance is the pH. The pH pH and pool water sets the tone for your water and keeps it clear and inviting.
Total Alkalinity (TA), refers to the alkaline materials dissolved in the pool water. Your water’s ability to resist pH changes depends on the alkaline material. Low TA can cause the pH to vary in and out of range. High TA makes it difficult to adjust the pH as needed.
Calcium Hardness is the amount of dissolved minerals (mostly calcium carbonate) in your water. Low Calcium Hardness calcium hardness problems can corrode equipment or etch a plaster finish. High levels can lead to cloudy water or scaling. Be sure to bring a water sample to your pool professional. They can analyze the water and provide you with the necessary instruction to ensure proper water balance and chlorination levels in your pool.
