Salt Water Pool Maintenance: How to Balance the Alkalinity Level with the pH Level
Pool owners and operators need to pay close attention to the water chemistry when tending to salt water pool maintenance. The chemistry parameters control the chemical’s equality in the pool water. Alkalinity is an acid formed from the result of alkaline materials like hydroxides, carbonates, and bicarbonates. It helps prevent big variations in the pH when there are small amounts of acid added in the pool. PH is the measure of hydrogen ion concentrate in water. PH affects all the other chemical balances in the pool. Alkalinity levels and pH levels need to stay balanced. The items and instructions needed to ensure the two stay balanced are listed below.
Step 1 – Prepping Pool
Pool should be vacuumed and swept, and water should be filled to correct level.
Step 2 – Testing the Filter and Pump
The filter and the pump will now need to be run through the testing portion and the chemical addition process.
Step 3 – Testing Water Samples
Get the water testing kit that will test the alkalinity, the pH and the calcium hardness. Do two tests of the water samples. This will assure you of an accurate test result reading. Before adding anything, figure out how much you will need to add and what component you need to add based on the gallon water amount in the pool.
Step 4 – Adding Alkalinity
The alkalinity increaser bucket will give you the proper amount of it to add. The alkalinity range for the pool is anywhere between 80 to 120 parts/million. The required amount is to be separated in 3 parts and add them in ten minute increments.
Step 5 – Running another Test
Test the water again after each of the 3 parts you add. This will let you know if you need to add all 3 of the parts you divided (prevents over dosing).
Step 6 – pH Testing
After you have added the right amount of alkalinity increaser, test the pH. Alkalinity increases the pH level. Either pH minus or the pH plus will need to be added to get the range from 7.2 and 7.8. Distribute the pH plus as you need it. Add the amount of pH minus needed to a bucket of pool water and dump into the skimmer. PH minus is extremely acidic and should be handled lightly.
Step 7 – Calcium Hardness Levels
Use the results of the test to measure the correct amount of calcium hardness increaser. This measurement dosage will need to be separated in three just as the alkalinity increaser was. Wait 10 minutes between each dose. The calcium hardness range should be between 180 and 240 parts per million. This is another harsh chemical to handle and the bucket method is advised.
Step 8 – Adding Sanitizer
Once all the chemicals balancing have reached their correct range, add chlorine or your chosen sanitizer.
