EZ SPA EZ3 Care Kit
Product Overview
A three-part weekly maintenance bundle engineered to balance, clarify, and sanitize 500 to 700-gallon hot tubs without measuring individual bottles.
API designed the EZ3 Spa Care Kit to eliminate water management guesswork by combining a concentrated sanitizer, water clarifier, and softening conditioner in pre-measured doses. Formulated for 500 to 700-gallon spas, the three components work together to destroy bacteria, coalesce microscopic particulates for the cartridge filter, and suppress foam. The system works alongside existing chlorine, salt, or bromine sanitizing routines while protecting internal pump seals and heating elements from scale formation.

Benefits & What Makes It Different
Three-Stage Treatment System
Combines targeted sanitation, particle flocculation, and water conditioning into a synchronized weekly application.
500 to 700-Gallon Calibrated Dosing
Eliminates calculation errors and chemical overcorrection by matching standard portable spa water capacities.
Broad System Compatibility
Formulated to integrate smoothly with chlorine, bromine, mineral cartridge, and ozone setups without causing surface staining.
Product Details
Sodium Dichloro-s-triazinetrione (Sanitizer), Polymeric Flocculant (Clarifier), Borate Conditioning Complex (Conditioner)
1 pre-measured dose pack per 500–700 gallons weekly or after heavy spa usage
Compatibility
- Compatible with chlorine, bromine, ozone, and mineral purification systems
- Safe for acrylic, fiberglass, and rotomolded hot tub shells
- Never pre-mix the dry or liquid components together in the same container
When To Use This
Pro Tip
In geographic areas with high calcium tap water, balance total alkalinity between 80–120 ppm before adding the conditioner; this prevents the softening minerals from causing temporary cloudiness when interacting with dissolved carbonates.
Common Questions & Instructions
How do EZ Spa chemicals work in hot tubs running on bromine?
The EZ3 Care Kit is fully compatible with bromine systems. The clarifier and water conditioner components function identically regardless of residual sanitizer type, while the sanitizer boost aids in breaking down bather waste without disturbing baseline bromide banks.
How long should I wait to soak after adding the EZ3 Care Kit?
Allow your spa jets to circulate on high for at least 15 to 20 minutes with the spa cover off. Once free chlorine tests between 1–3 ppm (or bromine matches target levels) and the water tests within pH 7.2–7.6, the spa is safe for bathers.
Does the EZ3 kit impact total alkalinity or calcium hardness?
The non-foaming formula is pH-balanced to minimize drift. However, your water should already sit within target ranges—total alkalinity 80–120 ppm and calcium hardness 200–400 ppm—prior to dosing to ensure the clarifying and conditioning agents work efficiently.
