Know your water.

A small smart monitor lives in your pool's pump housing, reads its chemistry live, and tells you exactly what to add — and when. No more guessing, no more test strips at dawn.

Join the waitlist — be first when NerraFlow launches in Australia.

The problem

Pool chemistry is a guessing game.

Strips fade, readings drift, and by the time the water's cloudy the damage is done. Whether it's your backyard or two hundred client pools, you're flying blind between visits — and every surprise is a callout, a chemical over-dose, or a green pool.

How it works

Live water, one clear instruction.

1

It reads

The device sits in the pump/filter compartment and measures pH, sanitiser, temperature and salt continuously — like a fitness band for your pool.

2

It thinks

NerraFlow turns the numbers into water balance and catches a problem forming before it's visible — then works out the exact dose for your pool's size.

3

It tells you

"Add 400 g of chlorine now." One plain instruction on your phone, plus alerts the moment something drifts. That's it.

For pool service companies

Your whole fleet, one screen.

See every pool you manage at a glance — green, amber, red — sorted worst-first. Catch the problem pool before the phone rings, skip the truck-rolls that weren't needed, and turn up already knowing what to bring.
