You bought a hot tub to relax. Instead, you got a part-time job.
The testing ritual
Dip strips, wait, squint at colors, Google what "high alkalinity" means. Repeat 2-3 times per week. Forever.
The guessing game
"A capful? A tablespoon? The whole bottle?" Add chemicals, hope for the best, check again tomorrow.
The surprise visits
Guests coming tomorrow. Race to the hot tub store. Shock it. Pray it clears in time. Sound familiar?
The hidden costs
Overdosing wastes chemicals. Underdosing ruins equipment. Either way, you pay—in money, time, or both.
What if your hot tub just... handled itself?
What if your hot tub just... worked?
The AutoChlorinator™ floats in your tub, tests the water automatically, and doses exactly what's needed. You refill it every few months. That's it.

How It Works
The AutoChlorinator™ uses intelligent water testing and automated chemical dosing to maintain perfect hot tub water chemistry automatically.
Continuous Water Testing
The device continuously monitors chlorine levels in your hot tub water, testing multiple times per day to detect when treatment is needed.
Smart Dosing Calculation
Based on current water conditions, usage patterns, and water volume, the system calculates the exact amount of chlorine needed—no more, no less.
Automated Treatment
The AutoChlorinator™ automatically dispenses the precise chlorine dose directly into your hot tub water, maintaining optimal sanitizer levels 24/7.
Continuous Monitoring
The cycle repeats automatically, adjusting to changing conditions like heavy use, temperature changes, or rain contamination.
