With a strong, resilient CGT vinyl pool liner, you have ensured that your pool liner remains the focal point of your pool. We have designed and manufactured our CGT vinyl to help your pool liner survive the extremes of nature, sun, heat, chemicals and the harshest conditions of winter.
Liner Care and Maintenance
Our specially formulated vinyl gives extended protection against biological growth and pattern loss. However, maintaining the chemistry of your pool water at recommended levels is essential to prolonged liner life as most liner problems are due to a misuse of chemicals, either too much or too little. For the proper chemical balance, your dealer can provide you with the test kits to measure the chemicals in your pool water. CGT recommends maintaining pool water chemistry at the following levels to maximize the life of your vinyl liner.
- Check Total Alkalinity
Your water test kit or your dealer’s test will show a total alkalinity reading. Simply put, it’s the ability of your pool water to counteract changes in the pH level.
Recommended—Total alkalinity level: 80-120 ppm
- Check pH
pH is the measure of acidity/basicity level in your pool. A proper pH level (7.2 to 7.6) not only increases human comfort, but also helps chlorine clean your pool better, because chlorine needs a certain pH level to kill bacteria and algae effectively.
Recommended— pH: 7.2 -7.6
- Check Free Chlorine
Your water test kit or your dealer’s test will show a total free chlorine reading, which is the concentration of residual chlorine in water present as dissolved gas, hypochlorous acid, and/or hypchlorite ion.
Recommended— Free Chlorine Level: 1.0 – 3.0 ppm
- Check Chlorine Stabilizer
All outdoor vinyl pools should be routinely stabilized with cyanuric acid in a range between 25 ppm and 50 ppm. The use of stabilizer helps to maintain the free chlorine levels in an outdoor pool.
Recommended— Chlorine Stabilizer: 25 – 50 ppm
RECOMMENDED – Total alkalinity level: 80-120 ppm
RECOMMENDED – 1pH: 7.2 -7.6
RECOMMENDED – Free Chlorine Level: 1.0 – 3.0 ppm
RECOMMENDED – Chlorine Stabilizer: 25 – 50 ppm
Other Safety Checks
Use the recommended personal protective equipment (PPE) when handling any chemicals as per the chemical manufacturer’s directions. Only add one chemical of a time and allow each chemical to circulate throughout the pool before adding a second chemical. Remember to always pre-dilute your chemicals with water before addition to the pool. Certain combinations of chemicals at a high concentration can cause bleaching of the pool surface.
Test for the presence of dissolved metals because they may directly stain the vinyl liner or combine with calcium hardness to form discolored deposits.
Each CGT vinyl pool liner has a special transparent topcoat that protects the print pattern from abrasion and soil adhesion. To maintain its effectiveness, avoid using abrasive cleaning agents or cleaning aids.
Closing the pool
At the end of the pool season:
- Test pool water.
- Never close a pool without circulating the pool water for several hours after the final additions of chemicals (chlorine may settle in the deep end and bleach the liner).
- Clean and vacuum the pool from top to bottom.
- Adjust the water for winterization.
*CGT PRO TIP
Use a proper fitting winter pool cover, tightly sealed around the perimeter of the pool. It will prevent the accumulation of debris such as leaves and insects during the off season. Should you have any questions about your pool, call your dealer – they are your pool professionals.
