## What is Pool Chemical Calculator Pro?

The pool is green and people are coming Saturday. You shocked it twice. Still green.

You just tested your pool water. The numbers mean nothing to you.

pH 7.8. Alkalinity 150. Free chlorine 1.5. CYA 60. Now what? Which chemical do you add first? How much? Do you wait between them? The chlorine bucket says "1-3 ppm" but your pool keeps turning green anyway.

The pool store will happily sell you $400 of chemicals you don't need. The forums will tell you to "just read the sticky." The other apps will show you a number and leave you staring at it.

Poolably tells you what to do.

Enter your test results. Get a numbered plan:

1. Add 16 oz muriatic acid to lower alkalinity → target 80
2. Wait 30 min. Re-test pH.
3. Add 52 oz liquid chlorine to raise FC to 6 (your CYA is 60, so you need at least 5 — not the "1-3" on the bucket)

Every step tells you why. Alkalinity before pH, because lowering one lowers the other. Chlorine last, because pH affects how well it works. Wait times between additions so they don't cancel each other out.

This is what "pool chemical calculator" actually means — not a number on a screen, but a plan you can walk outside and follow.

YOUR CYA IS PROBABLY WRONG

The #1 reason pools stay green despite constant shocking: cyanuric acid (CYA) is too high, and nobody told you that your chlorine target changes with it. If your CYA is 80, you need FC of 6-8 — not the 1-3 that every chlorine label says. Every pool store test ignores this. Poolably doesn't. Your chlorine target adjusts automatically based on your actual CYA reading.

SEE THE RESULT BEFORE YOU POUR

Tap any recommendation and see exactly what your water chemistry will look like after you add it. No surprises. No "I think I added too much." Adjust the dose, see the numbers move, then commit when you're confident.

STOP FORGETTING WHAT YOU DID LAST WEEK

Log test results in seconds. See trends over days, weeks, and months. Spot patterns — "pH spikes every Monday after weekend pool parties" — that you'd never catch testing blind.

Track every chemical you own. When you follow a treatment plan, inventory drops automatically. Get a heads-up before you run out mid-treatment.

At the end of the season, see exactly what you spent. Compare it to last year. The average pool service customer spends $1,200-$4,800/year. DIY owners who know their chemistry spend $300-$500. Now you have the receipts.

POOLS, HOT TUBS, AND SALT WATER

Chlorine, saltwater, bromine — all supported with correct chemistry for each. Hot tubs and spas get their own parameter ranges (not pool defaults crammed into a smaller volume). Run multiple pools and spas from one app.
