Answer a few plain-English questions, or ask your own ("what's sodium bicarbonate for?") — it fills out the calculator below for you as you go.

Your setup

Changes which pH/alkalinity products we suggest — liquid muriatic acid can damage liners and gelcoat if it's not what your pool tech would actually use.
Variable-speed: running longer at low RPM usually beats running less at high RPM — we'll suggest a speed alongside the schedule.
Check your pump's spec plate. For VS pumps, use the wattage at your usual filtration speed.
We don't have a direct utility account connection yet — this searches for your utility's published rate plans and estimates typical peak/off-peak pricing for you to confirm.

New pool? Here's what a pro would check that you wouldn't know to ask.

Generated from your setup above — this changes based on your sanitizer and filter type.

Test your water, get the fix — not just a schedule

Enter what your test strip or kit says. Rules-based pool chemistry math computes the dose; a rotating pool of AI models explains it in plain language and flags anything tied back to your filtration schedule.

Latest test results

Take a photo of the wet strip against its color chart, or skip and enter numbers manually below.
Not everyone runs borates — leave blank to skip. Pros use it as a buffer that helps hold pH steady and adds mild algae resistance.
Salt pools: TDS runs high because of the salt itself — a rough estimate is your salt reading plus ~500.
This is what makes it act like a pro instead of a one-off calculator — deviations here adjust your sanitizer output next round.
Approximate guidance only — always follow your product's label for exact dosing.

Water status

Explanation engine: rotating free-tier AI (auto-upgrades to Claude API on the subscription tier)

Free shows today's read. Subscription logs every test, tracks trends over the season, and ties chemistry swings (like an algae bloom) back into an updated pump schedule automatically.

Test history

Maintenance log

Backwashing, vacuuming, filter cleaning — tracked the same way as your water tests, and fed into the AI assistant so it knows what's already been done.

Leak or just evaporation?

Normal evaporation runs roughly 1/8"–3/8" per day depending on heat, wind, and humidity — more than that consistently is worth investigating as a possible leak.

Based on today's test, here's what would fix it

Same active ingredient as the pool-brand version, priced fairly — generic bulk chemicals, sourced through drop-ship suppliers, modest markup instead of specialty-label pricing.

Fulfilled by drop-ship suppliers, not SimplerPool directly — prices shown are estimates. We only suggest a recurring subscription for things people actually run out of; one-time-per-season items stay one-time.

Get ahead of the weather, not behind it

Heavy rain dilutes your chemistry. Heat spikes chlorine demand and algae risk. This checks your forecast against your last test and today's setup, so you catch it before it becomes a problem — the same idea a good pool tech uses when they glance at the sky. Subscription feature.
