Clear, sunlit pool water

Most pool problems are a mismatch: a pump too big for the filter, a salt cell too small for the gallons. Check the numbers first.

Decide with numbers

Calculators and quick answers

Our calculators use the same maker figures as our product pages and show their working.

Pump and filter size

Gallons and turnover to the flow you need, and the pumps and filters rated for it.

Pool volume

Gallons for rectangle, round, oval and kidney pools from size and depth.

Salt system size

The rated gallons to look for, with headroom, and the systems and cells that have it.

Heater size

BTU per hour to warm your pool by the degrees you want, in the time you want.

How Chlority works

A reference, not a review blog

Makers' own figures

Flow, filter area, rated gallons and heating output come from each maker's or seller's own published specifications. If a maker doesn't state something, we say so instead of guessing.

The part that fits

Cartridges and salt cells are matched to the part numbers their listings say they replace, so you can check against the label on your own equipment.

Sized to your pool

Our calculators start from your gallons and show every assumption, from turnover time to pipe resistance. How we research.
