All-in-One Pool Water Test
Enter your full test results below and we'll build a basic dosing checklist for everything that's out of range.
Your dosing checklist
Safety first
- Never mix chemicals together.
- Always add the chemical to the water — never water to the chemical.
- Wear gloves and eye protection when handling pool/spa chemicals.
- Keep chemicals out of reach of children and pets.
- Always follow the product label — it overrides any guidance here.
How this plan is built
Each parameter gets checked against its ideal range, then listed in the order you should actually fix it: alkalinity and pH first, then CYA, then chlorine, then calcium hardness — with a wait time between each step, free, no account needed. The quantities default to liquid chlorine at 12.5% and calcium chloride at 100% purity — switch to the individual calculators if you're using something else.
Frequently asked questions
What order should I add chemicals in?
As a general rule: fix alkalinity and pH first (they affect everything else), then CYA if needed, then chlorine/shock, then calcium hardness. Always wait and retest between additions rather than dumping everything in at once.
Is the sequenced order and wait times really free?
Yes — the numbered steps, doses, and wait times above are free for everyone. Pro (coming soon) adds saving your test history, tracking trends over time, and reminders to re-test — it doesn't change what the free plan already calculates.
Do I need to fix every parameter every time?
No — only add what's outside its ideal range. Parameters already in range are left out of your plan.
