Aquaculture water quality monitoring

Protect your stock with real-time water quality data.

AERO continuously measures dissolved oxygen, pH, temperature, salinity, TDS and turbidity in every pond. It alerts your team the moment a parameter leaves its safe range and runs aerators and dosing pumps automatically to bring water quality back into balance.

Why water quality matters

Water quality decides how your stock grows, and whether it survives.

Fish and shrimp live in the water they breathe. When dissolved oxygen falls, pH drifts or temperature climbs, animals become stressed, stop feeding and grow more slowly. They also become more vulnerable to disease. A severe oxygen drop can cause losses across an entire pond within hours.

These changes rarely happen while someone is standing at the pond. Dissolved oxygen is usually lowest just before dawn, after a night in which algae, fish and bacteria consume oxygen and nothing produces it. Heavy rain, a plankton die-off or a hot, still afternoon can shift water quality just as quickly. Testing by hand once or twice a day misses most of these events.

AERO closes that gap. Its solar-charged controller runs continuously, so it measures the parameters that matter around the clock, records every reading, and acts on the result, so problems are corrected early instead of discovered too late.

From the pond to your dashboard

Water quality probes in the pond report to an AERO controller on the bank. The solar-charged controller sends each reading to the cloud over the mobile network, where it appears in the Chekaero app, and switches your equipment when conditions require it.

1. Measure

Submerged probes measure dissolved oxygen, pH, temperature, salinity, TDS and turbidity. Additional sensors record rain, humidity, motion and dosing tank levels.

2. Respond

Each controller drives eight relays for aerators, dosing pumps, lights and a siren. When a parameter moves out of range, it starts the equipment that corrects it, without waiting for someone to act.

3. Manage

Your team sees every pond in the Chekaero app: current readings, alerts, history and equipment status. Adjust limits and switch equipment from any phone or computer.

Parameters

A complete water quality profile for every pond

Each parameter tells you something different about the health of your pond. AERO measures them together, so you can see how they affect one another.

Dissolved oxygen

mg/L

The most critical parameter in aquaculture. Low oxygen causes stress, poor feeding and, at worst, mass mortality. Many warm-water species need roughly 5 mg/L or more.

pH

0–14

Measures acidity. pH rises during the day as algae photosynthesise and falls at night. Large swings stress animals and change how toxic ammonia becomes.

Water temperature

°C

Controls metabolism, feeding rate and growth. Warmer water also holds less oxygen, so temperature explains much of the daily oxygen cycle.

Salinity

PSU

The concentration of dissolved salts. Each species has its own tolerance, so salinity matters for freshwater, brackish and marine culture alike.

Total dissolved solids

ppm

All minerals and compounds dissolved in the water. A steady rise shows build-up between water exchanges.

Turbidity

NTU

How cloudy the water is. It reveals sediment from runoff, a heavy plankton bloom or a sudden die-off that will consume oxygen.

Track water quality trends over time

A single reading tells you where a pond is now. A trend tells you where it is heading. Chart any parameter by hour, day, week or month, with your minimum and maximum limits drawn on the chart, so a falling oxygen curve is visible before it becomes an emergency. Export the data for records, audits or advisers.

Hour, day, week, month

Examine a single difficult night in detail or compare water quality across a whole production cycle.

Automatic correction, not just monitoring

Monitoring tells you there is a problem. AERO also acts on it. Each relay can respond to water quality readings automatically, follow a schedule or be switched by hand from the app.

Automatic or manual

Enable automation for each relay individually, or override it with a single switch when you need direct control.

Schedules

Set run times for aerators, lights and other equipment that follows a daily routine, such as extra aeration through the night.

Tank monitor

See the level of each dosing tank and the pump it supplies, with a warning before a tank runs empty.

One-tap corrections

Fix pH, Fix DO and Fix MO start the matching dosing pump immediately when a reading drifts.

Clear alerts your team can act on

Every alert states the pond, the parameter and its current value, with the time it was detected and whether it has been resolved. Your team knows exactly what is wrong and where, without opening a single chart.

Filter and resolve

Filter by pond, parameter and date range, then resolve or remove alerts individually or in bulk.

Repeat until resolved

Choose how often an open alert repeats, for all ponds or for one, so a critical reading is never overlooked. Emergency alerts are kept in their own list.

Our story

Six years of development behind the first AERO board

Chekaero was founded in 2020 on a commitment to aquaculture and a conviction that well-engineered technology could help fish and shrimp farmers protect their stock and run more profitable operations.

Turning that idea into a controller that measures water quality and operates farm equipment around the clock, at the pond's edge, proved more demanding than anticipated. The controller board went through more than ten design iterations, each one built, tested on the bench and in the field, and refined. The work took longer than planned and met delays along the way. In 2026, the first AERO board was completed.

Frequently asked questions

Answers to the questions farm owners and managers ask most often.

Which water quality parameters does AERO measure?

Dissolved oxygen, pH, water temperature, salinity, total dissolved solids (TDS) and turbidity. Each site can also record rain, humidity, motion at the pond edge and dosing tank levels.

Why is dissolved oxygen so important?

Oxygen is the parameter that changes fastest and causes the most losses. It typically falls overnight and reaches its lowest point before dawn. Continuous monitoring with automatic aeration prevents most oxygen-related mortality.

Can I set my own safe ranges?

Yes. Set a minimum and maximum for each parameter to suit your species, stage of production and local conditions. Alerts and automatic responses follow the limits you set.

Where do I use Chekaero?

Sign in at chekaero.app from any phone, tablet or computer to see your ponds, alerts and controls.

Can I monitor several ponds?

Yes. Each pond has its own controller, readings and alerts, and the dashboard brings all of them together.

Does the controller need mains power?

The AERO controller has solar charging for 24/7 operation. It keeps measuring water quality and sending data to the cloud through the night and during power cuts on site.

How do I know a controller is still reporting?

Every pond shows the date and time of its last update, so a controller that has lost power or signal is easy to spot.

Can it run equipment on its own?

Yes. Each relay can respond to readings automatically, follow a schedule or be controlled by hand from the app.
