Pool math shouldn't be a guessing game.
Most pool owners are either overdosing on chemicals or flying blind. We built the tools to fix that. No account, no guesswork, instant results.
No Guessing
Exact chemical amounts, every time

From test strip to answer
Any Pool
Salt, chlorine, pH, alkalinity, CYA
We built this because the alternative was a 2014 forum thread.
Pool ownership looks simple until you're standing at the edge holding a test strip, staring at a number, and Googling "how much salt to add to a 15,000 gallon pool." Then you fall into a rabbit hole of forum posts, conflicting advice, and calculators that need an account for some reason.
The information existed. It was just impossible to find quickly. Buried in PDFs, behind paywalls, or wrapped in so much noise that most people gave up and called a service — or worse, just dumped chemicals and hoped for the best.
So we built mypoollab: one clean place where you put in your pool volume and current levels, and get back an exact number. No login. No subscription. No upsell. Just the math.
