ChlorBench is an independent site that works out pool volume and the chemical doses that follow from it.
It exists because every pool dose is volume multiplied by a constant, and pool owners are handed the constants without ever being told the volume — which is the number that actually has to be right.
Where the numbers come from
- the 7.48 gallons per cubic foot conversion, and the standard volume formulas by pool shape
- published active-chlorine percentages for cal-hypo, dichlor, trichlor and liquid chlorine
Every page states the source and the assumptions behind its figures, because a number without its assumptions is not much use. Where a dose rate is a label recommendation rather than a measured value, the page says so.
Volume is the number worth getting right
Every dose a pool will ever need is volume multiplied by a constant, which makes volume the most valuable number in pool care — and most people are using the figure from a brochure rather than one they measured. Get it wrong by a fifth and every chemical for the life of the pool is wrong by a fifth.
What this site does not do
We do not give advice on pool equipment repair, electrical bonding or anything involving the pump circuit. Water and electricity together is a licensed trade.
Who runs it
One person with a pool and a habit of checking the arithmetic on the bucket. No editorial team. What should earn your trust is that every dose rate names the product label or standard it was taken from.
The chemistry runs as code across every pool shape, depth and product on the site, so a wrong constant would show up in hundreds of places rather than hiding in one. Errors are corrected and the correction is noted on the page.
How it is paid for
ChlorBench is free to read and funded by display advertising. No sponsored placements, no affiliate links. No chemical brand has any influence over what these pages recommend.
