Hot Tub Essentials

Essential hot tub chemicals are the core spa water treatment products needed to keep your hot tub clean, safe, and balanced. These typically include sanitiser (chlorine or bromine), pH balancers, shock treatment, and water testing products for ongoing hot tub water care.

The main hot tub chemicals include chlorine or bromine sanitiser, pH increaser, pH reducer, alkalinity increaser, shock treatment, and spa test strips. These products work together to maintain safe and balanced hot tub water.

Hot tub chemicals should be checked and adjusted regularly, typically several times per week depending on usage. Sanitiser levels, pH balance, and alkalinity should be monitored frequently to maintain safe spa water.

Without proper hot tub chemical treatment, water can quickly become contaminated with bacteria, algae, and body oils. This can lead to cloudy water, skin irritation, and damage to your spa system.
