Questions
Why is weekly pool shocking necessary?
Shocking oxidizes contaminants that regular chlorine tablets miss, maintaining water clarity and preventing algae growth without lowering pH levels.
How does pH affect my pool?
Proper pH (7.2-7.6) prevents equipment corrosion, swimmer discomfort, and chemical inefficiency. Imbalances cause liner damage and skin/eye irritation.
When should I backwash my filter?
Backwash when filter pressure rises 8-10 psi above normal or water flow decreases. Regular maintenance restores filtration efficiency and extends equipment life.
How often should spa water be changed?
Spa water typically requires changing every 3-4 months depending on usage and chemical maintenance to maintain hygiene and equipment performance.
Can I use household products for pool maintenance?
While baking soda can raise alkalinity slightly, professional-grade chemicals ensure proper balance and prevent equipment damage from improper formulations.
