Spa water is cloudy and does not clear even with filtration running

Safety: Handle chemicals with care and follow label directions.

• Clean filters thoroughly: Remove filters and hose them off from top to bottom. For heavily soiled filters, soak in a filter cleaner overnight and rinse well.
• Increase filtration time: Use the topside control to extend daily filtration cycles so more water passes through the filters.
• Shock the water: Add a clarifying shock treatment to oxidize organics. Run all pumps to circulate.
• Use a clarifier (optional): Add a spa clarifier to help small particles clump together so the filter can capture them.
• Check and adjust water balance: Test pH, alkalinity, and calcium hardness. Adjust to Bullfrog's recommended ranges.

If cloudiness persists, consider draining and refilling, especially if the water is old (3–4 months or more).
