Buying Guide
What size should you choose for your pool?
- Match the system to your pool’s gallon capacity. Undersized units struggle to maintain chlorine balance in larger pools.
- Consider future expansion. If you plan to grow your pool, a higher-capacity system may be more economical long-term.
What features matter most?
- Monitoring: Real-time displays, app access, and wireless alerts help maintain optimal sanitizer levels.
- Cell maintenance: Self-cleaning cells reduce manual cleaning; reverse polarity helps control scaling.
- Durability: Metal control boxes tend to resist wear and weather exposure better than plastic in harsh climates.
Installation considerations
- Ease of installation: Some units are plug-and-play, while others need professional plumbing adjustments.
- Compatibility: Check plumbing fittings (inlet/outlet sizes) and electrical requirements with your current system.
- Maintenance plan: Consider how often you’ll inspect the cell and replace components to keep the system operating efficiently.
