@poolpro

I used to rely on liquid chlorine. Since I got SunnyWhale, I just load the tablets and the machine dispenses chlorine throughout the day — it's solar-powered and only needs a charge every 1.5 to 2 weeks. The app tells me chlorine levels, pH, and water temp from anywhere. My pool's been nice and clear ever since. I recommend it.

I'm one of those people that really likes to sit here and test my pool, make sure all the levels are proper. I have my own, you know, the chemical testing kits, the whole works — a professional level all the way across the board, doing chlorine tests every other day, making sure that the buffers, the cyanuric acid, everything is in perfect ranges. So, highly recommend it. It's an awesome product.

After a few days with the Pro 2, I'm truly impressed. The image quality is stunning with high brightness, deep contrast, and the EBL.

The Essentials of Water Care — Simplified.

Because clear water shouldn't require a chemistry degree.

What is pool chlorine and why does it matter?
The best chlorine system depends on how much control and visibility you want over your pool water.
Traditional floating dispensers and inline feeders release chlorine at fixed or manually adjusted rates, which can lead to inconsistent levels as conditions change.
Salt systems automate chlorine generation but are expensive and may not provide full insight into water balance.
Smart systems like FinWhale take a more adaptive approach by monitoring water conditions in real time and adjusting chlorine output accordingly. This helps maintain more consistent levels while giving pool owners and professionals better visibility into overall water health.
What is a smart chlorine dispenser?
A smart chlorine dispenser like FinWhale™ automatically monitors your pool's water chemistry and dispenses the right amount of chlorine based on real-time sensor readings. Unlike traditional dispensers that release chlorine at a fixed rate, smart dispensers adapt to changing conditions.
How does a smart chlorine dispenser work?
FinWhale™ uses built-in sensors to continuously measure chlorine, pH, ORP, and water temperature. It calculates the ideal chlorine demand and automatically adjusts its dispenser valve to release chlorine tablets at precisely the right rate. All data syncs to the SunnyWhale app in real time.
Is FinWhale™ compatible with my pool?
FinWhale™ is designed for residential in-ground and above-ground pools up to 25,000 gallons. It works with standard 1 or 3-inch chlorine tablets and is compatible with fresh water pools, vinyl liner, fiberglass, and concrete pools. No installation required — simply float it in your pool.
