Persistent foamy water even after rinsing filters; foam increases when jets are on.

Safety first: Handle all spa chemicals with gloves and eye protection.

• Test water: Use a test strip or kit to check pH, alkalinity, and calcium hardness in your Everlast spa.
• Shock treatment: Add a non-chlorine shock or chlorine shock per Everlast and chemical manufacturer guidelines to oxidize contaminants.
• Adjust hardness: Raise calcium hardness to recommended levels to reduce foaming.
• Drain and refill: If foam persists, drain the spa completely, wipe the shell, clean or replace Everlast filters, and refill with fresh water.
