You should never add stabilizer (cyanuric acid, CYA) directly to your saltwater pool because it dissolves very slowly and can damage the pool surface. Instead, follow these steps:
Steps for Adding Stabilizer
-
Determine the Required Amount: Test your pool water to determine the current CYA level. The ideal range for a saltwater pool is typically between 70-80 ppm. Use a pool calculator (many are available online from pool supply retailers) to determine how much stabilizer you need to add to reach the target level. It is crucial not to over-stabilize your pool.
-
Pre-Dissolve the Stabilizer (Recommended): The safest and most effective method is to pre-dissolve the stabilizer.
- Bucket Method: In a large, clean bucket, slowly add the stabilizer to warm water while stirring. Use a separate stirring tool and avoid using items that will be used for food preparation. It can take a while to dissolve, so be patient and continue stirring periodically.
-
Slowly Add the Solution to the Pool:
- Pour Gradually: Once the stabilizer is dissolved (or mostly dissolved, if you are using the sock method), slowly pour the solution into the pool. Spread it around the pool's perimeter as much as possible.
-
Alternatively, Use a Sock (If Pre-Dissolving is Difficult): If pre-dissolving is impractical, you can use a clean sock or pantyhose.
-
Fill the Sock: Fill a clean sock or pantyhose with the measured amount of stabilizer.
-
Suspend in Front of Return Jet: Hang the sock in front of a return jet (where water flows back into the pool). This will help the stabilizer dissolve slowly. You can also manually squeeze the sock periodically to aid dissolution.
-
Monitor Dissolving: It can take several days for the stabilizer to fully dissolve using this method. Continue to monitor the sock and squeeze it periodically until all the granules are gone.
-
-
Run the Pool Pump: Run your pool pump continuously for at least 24 hours (and preferably 48 hours) to ensure the stabilizer is thoroughly mixed into the water.
-
Re-Test Water Chemistry: After 48 hours, re-test your pool water to confirm the CYA level is within the ideal range. If necessary, make small adjustments.
Important Considerations:
- Safety: Always wear gloves and eye protection when handling pool chemicals.
- Pool Surface: Avoid letting undissolved stabilizer sit directly on the pool surface, as it can cause staining or etching, especially on plaster or vinyl liners.
- Patience: Dissolving stabilizer takes time. Don't rush the process.
- Over-Stabilization: Adding too much stabilizer can reduce the effectiveness of chlorine, leading to cloudy water and algae growth.
