⚠️ Rain Tomorrow — Act Now

Forecast: 1.2" of rain at 3PM. Add 2oz of pH Up tonight to prevent alkalinity crash.

✅ Chlorine Levels Balanced

Free chlorine at 3.0ppm. No action needed. Next check in 18 hours.

🌡️ Heat Wave Alert

95°F expected Thursday. Increase pump runtime to 10hrs to prevent algae bloom.

How Pool Care Really Works

The chemistry is simple.
The timing is everything.

Most pool problems don't start with bad luck. They start the night before — when conditions shift and no one's watching.

🌧️

Why chlorine drops after rain

Rain dilutes your pool water and introduces nitrogen compounds that consume free chlorine. A single storm can drop FC by 1–2 ppm before you've had your morning coffee.

☀️

Why UV destroys chlorine faster than anything

Without a stabilizer (CYA), direct sunlight can burn through a large portion of your free chlorine in just a couple of hours. Hot summer afternoons are when algae gets its opening.

⚗️

Why pH never stays where you put it

Aeration, CO₂ off-gassing, swimmer activity, and product additions all push pH up or down steadily. It's not a problem you fix once — it's one you watch continuously.

🧪

Why test strips are hard to read consistently

Color-matching under outdoor light is genuinely difficult. Readings taken at different angles or in different lighting can vary enough to matter for pH and free chlorine decisions.

🌙

Why most pool problems start overnight

Algae grows fastest when the pump is off, the sun is down, and chlorine is at its lowest. The green pool you discover Monday morning started Saturday night.

🌡️

Why warm water accelerates everything

At higher temperatures, chemical reactions happen faster, algae reproduces faster, and chlorine burns off faster. Summer is when your pool needs the most attention — and gets the least.

What Most Pool Owners Don't Know

Four facts that change
how you think about your pool.

Most pool advice focuses on how to fix problems. SwimKeep focuses on what creates them — so you can act before it matters.

1

A stabilizer makes chlorine last 8× longer in sunlight

CYA at 30–50 ppm dramatically extends how long free chlorine survives UV exposure. Without it, you're pouring chemical into a bucket with a hole in the bottom.

2

Rain is slightly acidic and nitrogen-rich

Even moderate rainfall shifts pH and alkalinity while simultaneously consuming the free chlorine already in your pool. After a storm, your water is not the same water.

3

Heavy bather load can drop FC by 1–3 ppm in one afternoon

After a pool party, your chemistry is different. It doesn't announce itself. If you don't test after heavy use, you're flying blind into the next 24 hours.

Clear, grounded pool guidance

SwimKeep is built to help you log readings, review weather context, and make more confident pool-care decisions with less guesswork.

FAQ

Questions? We've got clear answers.

No. SwimKeep works with your existing pool setup and currently relies on the pool profile you enter plus manual or photo-based strip readings.

Chlorine, saltwater, and mineral pools are supported, including inground and above-ground setups. Guidance also takes your location, cover usage, and skimmer setup into account.

SwimKeep uses ZIP-based weather lookups and forecast data to add context to your pool guidance. Weather is one input alongside your latest logged reading, not a guarantee of exact pool conditions.

Subscription management depends on how the license was created. The dashboard shows your current license details and usage, and live billing management routes through the provider-backed license flow.

SwimKeep can work alongside your existing routine or pool service by giving you another view of recent readings, weather conditions, and recommended next steps between visits.
