Consistency Is the Difference Between Clear and Unpredictable

Traditional chlorine systems deliver chlorine at a fixed rate or rely on manual adjustment. As conditions change, chlorine levels can rise or fall unpredictably.

FinWhale™ is designed to maintain more consistent chlorine levels by responding to real-time water conditions.

Designed to work in your pool without plumbing or equipment changes.

*Start with Balanced Water
FinWhale works best when your pool water is already balanced. It helps maintain consistent FC (free chlorine) levels and supports easier pool care — but it is not a replacement for correcting existing water chemistry issues. Please test and balance your CYA and TDS before setup.

Why Traditional Chlorine Systems Fall Short
FinWhale smart chlorine dispenser product lifestyle image for summer pool care FinWhale smart chlorine dispenser package contents layout
FinWhale™ Smart Chlorine Dispenser
FinWhale™ takes a different approach. It monitors water conditions continuously, interprets what your pool needs, and dispenses chlorine accordingly, while giving you full visibility through the app.
Floating Chlorine Dispensers
Floating dispensers continually release chlorine over time, without any awareness of what your water actually needs. On cooler days, they can underperform. On hot, sunny days, they can’t keep up. This can lead to spikes and dips in chlorine levels.
Inline Erosion Feeders
Inline feeders improve control, but still rely on manual adjustment. They don’t adapt in real time, which means water balance can drift between service checks.
Salt Chlorinators
Salt systems generate chlorine automatically, but they don’t always provide visibility into overall water health, and performance can fluctuate with conditions. Installation and maintenance can also be expensive.

The Essentials of Water Care — Simplified.

Because clear water shouldn't require a chemistry degree.

How does FinWhale work?
FinWhale™ floats in your pool and uses built-in sensors to continuously test water chemistry every 20 minutes. Based on the readings, it automatically adjusts how much chlorine it releases to maintain proper sanitizing levels.
How often do I need to refill it?
FinWhale™ holds standard 1-inch or 3-inch chlorine tablets. Tablet Compatibility: Standard 1 or 3-inch tablets (up to 6 tablets for 3"). Refill frequency varies depending on pool usage, sun exposure, weather conditions, and bather load. Check the tablet compartment periodically and refill as needed.
Does it work with all pools?
FinWhale™ works with most residential in-ground and or above-ground pools up to 25,000 gallons, including vinyl liner, fiberglass, and concrete. Finwhale currently supports chlorine pools only. Salt pool support is on our roadmap.
How much chlorine should a pool have?
Most health authorities recommend maintaining free chlorine levels between 1.0 and 4.0 ppm. FinWhale™ is designed to maintain your pool within this ideal range automatically.
What is free chlorine?
Free chlorine is the active form of chlorine available to sanitize your pool water — the most important measurement for pool safety.

@influencer

FinWhale automatically dispenses chlorine, replaces test strips, and lets me monitor my pool from the app. It keeps my water balanced with almost no effort. I highly recommend it

@influencer

I use the FinWhale Smart Chlorine Dispenser to help me manage my pool. It automatically measures key parameters like pH, water temperature, and ORP, and allows me to monitor the pool anytime through a mobile app. For me, this device is very practical, as it makes it easier to maintain the pool independently and lets me adjust and check the readings whenever it’s convenient for me.

@influencer

I’ve been using the FinWhale device for about a week now, and I’m honestly pretty impressed. Setup was simple, and it’s been running smoothly ever since. The battery performance has been stable, and I haven’t had to worry much about constant adjustments. It just makes pool maintenance feel a lot easier and more under control.

@influencer

FinWhale helps monitor my pool water and automatically dose chlorine, making pool maintenance much easier to manage. It gives me peace of mind knowing the water is being taken care of, and I feel much more confident hosting the upcoming pool party for my family and friends.

@influencer

FinWhale has saved me a lot of time on pool maintenance and keeps my pool water much more stable. It's especially helpful for families like ours with sensitive skin, since consistent water quality is really important.

Customer review photo showing FinWhale smart chlorine dispenser pool care experience

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.

Video thumbnail showing SunnyWhale pool care user story

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.

Customer review photo showing FinWhale smart chlorine dispenser pool care experience

FinWhale helps me monitor my pool's Free Chlorine, pH, ORP, and temperature in real time, while automatically dispensing the right amount of chlorine. It takes the hassle out of pool maintenance, so my family and I can enjoy a clean, healthy pool whenever we want.

Had my finwhale for a couple of weeks and absolutely love it. I have double checked the stats it supplies and they are spot on. I haven’t had to add a drop of chlorine since that time.

It truly will show its worth when we take off on a couple week vacation, and I think this will stall our plans to switch to salt.

Not sure why my ;newly-purchased unit allows (causes?) wildly fluctuating FAC readings within a few hours. Just put it in service last week so haven't reached out to customer service, so hoping they're quick and responsive!

Hi, thank you for sharing your experience. Some fluctuation in free chlorine (FC) readings over several hours can be normal, as readings may be affected by water circulation, sanitizer output, sunlight, temperature, recent pool use, and sampling conditions. However, we’d like to review the actual range of your readings to make sure the unit is operating as expected. Please contact us at sunnywhale@sunnywhale.net with your order number, pool setup, and a screenshot or short video of the readings. Our team will be happy to help.

Super Reassuring!

I used to worry about coming home to a cloudy or green pool whenever we went out of town. This time, I could check the chlorine level, pH, water temperature, and battery right from my phone. I knew I'd get an alert if anything needed attention, so I wasn't constantly wondering what was happening back home. It made leaving the pool for a few days a lot less stressful.

Had one since launch, makes pool maintenance WAAAAAY easier, and accurate, at my fingertips. As ‘set and forget’ as a chlorine dispenser coils ever be. Built in solar means I haven’t had to charge it once!
