1. Introduction
The Rx Clear Swimming Pool Stabilizer and Conditioner is a 100% cyanuric acid product designed to protect chlorine from degradation caused by the sun's ultraviolet (UV) rays. By stabilizing chlorine, this product helps maintain more consistent chlorine levels in your swimming pool, ensuring longer-lasting sanitation and balanced water chemistry.
Proper cyanuric acid levels are crucial for extending the life of chlorine and supporting overall pool water balance in both above-ground and in-ground pools. This product is typically added at the beginning of the swimming season to establish and maintain optimal stabilizer levels.

2. Safety Information
Always handle pool chemicals with care. Read and follow all instructions and warnings on the product label.
- KEEP OUT OF REACH OF CHILDREN.
- Avoid contact with skin and eyes. In case of contact, rinse immediately with plenty of water and seek medical advice.
- Do not ingest. If swallowed, do not induce vomiting. Call a poison control center or doctor immediately.
- Store in a cool, dry, well-ventilated area, away from incompatible materials and direct sunlight.
- Never mix this product with other chemicals, especially other pool chemicals, as dangerous reactions may occur.
- Wear appropriate protective equipment, such as gloves and eye protection, when handling.

3. Setup and Preparation
Before applying the Rx Clear Stabilizer and Conditioner, it is essential to prepare your pool water and test its current chemical levels. This ensures optimal effectiveness and prevents potential issues.
3.1 Initial Water Testing
Use a reliable pool test kit to check the current levels of cyanuric acid, chlorine, and pH in your pool water. This product is best applied when opening your pool for the season.
- Recommended Chlorine Residual: 2.0–4.0 ppm
- Recommended pH Level: 7.4–7.6
- Target Cyanuric Acid Level: 30–50 ppm (for initial application)

Ensure your pH and alkalinity are within the recommended ranges before adding stabilizer. If your pH is very low, adjust it with an alkalinity increaser first to ensure all chemicals work effectively.
4. Application Instructions
Follow these steps for proper application of Rx Clear Stabilizer and Conditioner:
4.1 Dosage Guidelines
- Use 2 lbs per 10,000 gallons of pool water as a general guideline.
- Always add stabilizer based on the amount of water being replaced, not the total pool capacity, for accurate level adjustment.
4.2 Dosage Chart
| Pool Size | 10 ppm Increase | 20 ppm Increase | 30 ppm Increase | 40 ppm Increase | 50 ppm Increase |
|---|---|---|---|---|---|
| 5,000 Gallons | 6.3 oz | 12.5 oz | 1.2 lbs | 1.6 lbs | 2.0 lbs |
| 10,000 Gallons | 12.5 oz | 1.6 lbs | 2.3 lbs | 3.1 lbs | 3.9 lbs |
| 20,000 Gallons | 1.6 lbs | 3.1 lbs | 4.7 lbs | 6.3 lbs | 7.8 lbs |
4.3 Application Method
- Ensure your pool filter is clean before application.
- Add the Rx Clear Stabilizer and Conditioner directly to the skimmer.
- Recirculate the pool water continuously for 24 hours to allow the product to dissolve completely and distribute throughout the pool.
- Avoid backwashing for at least one week after application to ensure the stabilizer fully integrates into the water.
This quick-dissolving formula disperses efficiently to establish chlorine protection. Adding too much too quickly can cloud your pool water.
5. Maintenance
Maintaining proper cyanuric acid levels is an ongoing process that contributes to overall pool health and chlorine efficiency.
- Regular Testing: Periodically test your cyanuric acid levels, especially after heavy rainfall or significant water replacement, as these can dilute the stabilizer.
- Replenishment: If levels fall below the recommended range (30-50 ppm), add more Rx Clear Stabilizer and Conditioner according to the dosage chart, based on the amount of water being replaced.
- Chlorine Efficiency: By keeping stabilizer levels correct, you help extend the usable life of your chlorine, reducing the frequency and amount of chlorine needed.
- This product supports balanced pool water and seasonal maintenance without affecting the type of chlorine you use or your pool system's compatibility.
6. Troubleshooting
While Rx Clear Stabilizer and Conditioner is straightforward to use, some issues may arise:
- Cloudy Water After Application: Adding too much stabilizer too quickly can temporarily cloud the pool water. Ensure proper circulation and filtration. If cloudiness persists, check other chemical levels (pH, alkalinity, calcium hardness) and ensure your filter is clean and operating correctly.
- Stabilizer Not Dissolving: Cyanuric acid can take time to dissolve. Ensure continuous circulation for at least 24 hours. For faster dissolution, some users place the product in a fine mesh bag (like a paint straining bag) and hang it in front of a return jet or in the skimmer.
- Cyanuric Acid Levels Not Registering: It can take several days for cyanuric acid to fully register on test kits after application. Do not re-dose immediately if initial tests show low levels; wait 3-7 days and retest.
- Chlorine Still Depleting Rapidly: If stabilizer levels are adequate but chlorine loss is still high, re-check your cyanuric acid levels with a fresh test kit. Also, ensure pH and alkalinity are balanced, as these affect chlorine effectiveness.
