Buying Guide: Key Purchase Considerations
- Pool size and usage: Larger pools or higher weekly usage may justify higher-volume or bulk packs.
- Water balance: Non-chlorine shocks should not disrupt pH; look for products that claim pH stability.
- Frequency and schedule: Regular dosing (weekly or biweekly) helps prevent buildup of contaminants and chloramines.
- Compatibility: Ensure the shock is compatible with your existing sanitizers and pool type (in-ground, above-ground, spa, hot tub).
- Dispersal method: Some shocks dissolve quickly; others may require slower mixing. Consider circulation and filter type.
- Odor and residue: Non-chlorine options can reduce harsh chemical odors and skin irritation.
- Safety and handling: Check labeling for protective measures and storage guidance.
