Pool calculators and diagnostic tools

Water and routine care

Use measured test results and a realistic pool volume. These tools do not test the water for you.

• Water chemistry — Calculate treatment from entered water results and pool volume, with Melbourne FC targets.
• Salt chlorinator — Check chlorinator sizing and operating assumptions for your pool volume.

Measurement and environment

Geometry, depth, weather and cover use can move these estimates substantially.

• Pool measurement — Estimate pool dimensions using satellite imagery from your address.
• Volume calculator — Estimate water volume in litres from pool shape and dimensions.
• Evaporation — Compare estimated daily water loss under temperature, wind and cover use.
• Image diagnostics — Upload photos so we can see equipment or water faults before the visit.

Heating, hydraulics and energy

Compare operating demand before choosing equipment. Confirm final sizing on site.

• Heat-up time — Estimate heating time from volume, temperature lift, cover and heater type.
• Filter sizing — Check filter capacity against pool volume and turnover assumptions.
• Pump optimiser — Compare pump run hours and seasonal turnover for Melbourne pools.
• Energy comparison — Compare estimated annual energy use across pump and heater setups.

Equipment and project planning

Prepare for a discussion — outputs are guides, not site-specific quotes.

• Equipment builder — Organise compatible equipment requirements around the pool pad.
• Pool cost calculator — Build a running-cost estimate from pump hours, heating and chemicals.
• Resurfacing return — Compare resurfacing inputs and potential value factors for older shells.
