FAQ

What kind of chemicals does this AquaChek set include?+

This AquaChem set primarily contains chlorine tablets, shock treatment solutions, algaecide tablets, pH up and down granules, and a selection of test strips. It’s formulated for general pool maintenance in UK swimming pools.

How often should I use the test strips?+

Ideally, you should test your water at least twice a week, or more frequently if your pool is heavily used or exposed to adverse weather conditions. Regular testing ensures accurate monitoring of chlorine and pH levels.

Are these chemicals safe for all types of pools?+

These AquaChem chemicals are designed for standard freshwater swimming pools. They are not suitable for saltwater pools, hot tubs, or spas without specific adjustments outlined in the product instructions.

How do I store the chemicals after opening?+

Once opened, it’s crucial to reseal the containers tightly with airtight lids to prevent moisture and air from affecting their potency. Store them in a cool, dry place away from direct sunlight and extreme temperatures.

What does a low pH reading indicate?+

A low pH reading (below 7) indicates that your pool water is too acidic. This can corrode pool equipment and irritate swimmers’ eyes and skin. You should add pH up granules to raise the pH level.

How do I know when to shock my pool?+

You should shock your pool after heavy use, swimming events, or periods of rainfall where contaminants may have entered the water. Shocking helps eliminate bacteria and algae that chlorine alone cannot handle completely.

What is the best way to measure pH accurately?+

Use a dedicated pH test kit like those included in this AquaChem set. Always follow the manufacturer's instructions carefully when using the test strips for accurate readings.

Can I use these chemicals with automatic chlorinators?+

Yes, many of these AquaChem tablets are compatible with automatic chlorinators. However, always consult your chlorinator’s manual for specific dosage recommendations to avoid over-chlorination.

What happens if the pH is too high?+

A high pH reading (above 7.5) indicates that your pool water is alkaline. This can reduce chlorine effectiveness and cause scaling on pool surfaces. Use pH down granules to lower the pH level.

Are these chemicals suitable for a small private pool?+

Absolutely! The AquaChem products are formulated for various pool sizes, including smaller private pools. Follow the dosage instructions based on your pool's volume for optimal results and water balance.
