Measure twice, dose once
We recently assisted one of our retailers in solving a dosing problem by examining the very fundamental issue of correct pool volume calculation.
The rectangular 48,000 L pool was measured incorrectly, with each error compounding the problem, leading to a large volume miscalculation as highlighted below.
Correct volume: 48,000 L.
Rounding: Rounded up to 50,000 L “because it is easier just to say my pool is 50,000 litres”. This is the volume the customer might tell you their pool is. When asked to properly measure their pool, the customer returns with these values.
Depth: Incorrect by 10 cm at each end. Pool volume reduced to 44,800 L.
Length: Incorrect by 1 m. (Easy to do over a 10 m span if measured by stepping it out.) Pool volume reduced to 39,200 L.
Width: Incorrect by 20 cm. Pool volume reduced to 37,200 L.
Steps: Overlooked; approximately 200 L unaccounted for.
In the end, the volume was miscalculated as 37,000 L — that’s a massive 23% difference! Consider now that every dose of chemical, or every treatment, was 23% too little.
Simple measurement inaccuracies can dramatically change litreage, resulting in incorrect chemical application. To avoid subsequent problems, always ensure pool and/or spa volume is strictly accurate before entering data into BioGuard Water or similar dosage calculating program.
