Pool Chemical Dosing Log

Record every chemical you add, with date, product, and amount, so you never guess whether you already shocked the pool this week.

Guesswork is where pool chemistry goes wrong: a double dose because you forgot the first, or a skipped one because you weren't sure. Skimmer's dosing log is a fast, timestamped record of exactly what went into the water and when.

What it does

Inside the feature

Fast entry at the equipment pad

Log a chemical addition in a few taps, product, amount, and date, right where you're standing, even with no signal.

A real answer to 'did I already do that?'

Your dosing history is always one glance away, so you stop double-dosing or forgetting a treatment.

Pairs with the dosing calculators

Work out the right amount in the free calculators, add it, then log what you actually put in, so the estimate and the record stay connected.

Frequently asked

Frequently asked questions

Can I log any chemical, or only the common ones?

Log any chemical addition with a product name and amount. Chlorine, acid, soda ash, baking soda, calcium, stabilizer, salt, algaecide, whatever you add goes in the same log.

Does the dosing log work offline?

Yes. Skimmer works fully offline, so you can log a dose at a property with no signal and it's simply there next time you open the app.

Can Skimmer tell me how much to add?

The app and the free calculators work out a starting dose from your pool volume and the gap to your target. You then log what you actually added.
