To excel at a pool store, employees should have knowledge of pool chemicals, basic water testing procedures, retail sales experience, and inventory management. Familiarity with point-of-sale systems, chemical testing kits, and possibly CPO (Certified Pool Operator) certification is beneficial. Strong customer service skills, good communication, and attention to detail help employees build trust with customers and maintain store standards. These qualifications ensure smooth store operations, accurate water treatment advice, and a positive shopping experience for customers.
