What this tool does
Volume is the number every chemical dose depends on, so getting it right once saves guessing forever after. Turnover time is how long the pump takes to push the whole pool through the filter — most guidance asks for the full volume to turn over within four to six hours.
Formula
volume = length × width × average depth

Limitations
- The result is an estimate based only on the values you type. Real situations often include factors this calculator does not know about.
- Coverage and consumption figures vary between products. Take the values from the manufacturer's datasheet for the product you are actually using.
