Arctic Pure | Smart pH Replacement Cartridges | 2-Pack

Smart pH Replacement Cartridges for Arctic Spas Spaboy System

Keep your hot tub water perfectly balanced with Arctic Pure Smart pH Replacement Cartridges. Designed exclusively for Arctic Spas equipped with the Spaboy automated salt water system, these cartridges work with the Smart pH module to automatically monitor and adjust your water's pH levels — so you spend less time testing and more time relaxing.

Each pack includes two 300g cartridges that gradually dissolve to lower pH and maintain optimal water chemistry. When your Smart pH system signals that a cartridge is running low, simply swap in a fresh one to keep automatic balancing running smoothly.

What's Included

• 2 x 300g Smart pH cartridges
• Compatible with all Arctic Spas models featuring Spaboy and Smart pH

Why Automatic pH Matters

Unbalanced pH can cause skin irritation, cloudy water, and premature wear on your spa's components. The Smart pH system checks your water continuously and makes micro-adjustments throughout the day, keeping pH in the ideal 7.2–7.8 range without manual dosing.

How Often to Replace

Cartridge life depends on usage and water conditions, but most spa owners replace them every 2–4 months. We recommend keeping a spare set on hand so you're never without automatic pH control.

Works With

• Arctic Spas Spaboy Salt Water System
• Smart pH Auto-Dosing Module
