FAQ
What type of chlorine tablets are included?+
This selection features granular and tablet chlorine options, catering to various dosing preferences. Granular chlorine is ideal for bulk dispensing, while tablets offer precise dosage control.
How often should I shock my pool?+
Shock treatment frequency depends on usage and environmental factors; generally, weekly or bi-weekly during peak swimming season is recommended. However, always assess water clarity and test regularly to determine the optimal timing.
What does pH affect in a pool?+
pH levels directly impact sanitizer effectiveness; low pH can corrode pool equipment and irritate swimmers’ eyes, while high pH reduces sanitizer potency. Maintaining a balanced pH is crucial for overall water quality.
How do I measure my pool's alkalinity?+
Alkalinity is measured using a test kit or strips and requires adding sodium bicarbonate if levels are too low, or muriatic acid if they’re too high to achieve the ideal range.
What’s the best way to prevent algae growth?+
Regularly applying an algaecide like Relax Alga Clear is essential. Maintaining proper chlorine levels and balanced pH also significantly reduces the risk of algae blooms.
Are these products safe for saltwater pools?+
Relax Pool Chemicals are formulated to be compatible with most saltwater pool systems, but always consult your pool equipment manufacturer’s recommendations regarding specific product usage.
What does ‘stabilizer’ in a chlorine tablet mean?+
Stabilizers, like cyanuric acid, protect chlorine from sunlight degradation. However, high stabilizer levels can reduce chlorine effectiveness; monitor and adjust accordingly.
How do I store these chemicals correctly?+
Store Relax Pool Chemicals in a cool, dry place away from direct sunlight and children or pets. Keep containers tightly closed to prevent evaporation and contamination.
What’s the difference between ‘shock’ and ‘sanitizer’?+
Shock treatment rapidly destroys contaminants, while sanitizers (like chlorine) provide ongoing protection against bacteria and algae. Using both together ensures a comprehensive water treatment approach.
Can I mix different Relax Pool Chemicals together?+
While generally safe, it's best to follow the manufacturer’s instructions carefully when combining chemicals. Always add products one at a time, allowing sufficient time for them to dissolve and circulate before adding another.
