Your aquarium stays stable, even when you’re away.
The Core follows a target for each hour, logs the water every 5 minutes and runs a full day of light, from sunrise to moonlight. You choose the species; it handles the rest, even offline.
No payment, no commitment. We'll let you know when the first batch opens. We only use your email for this. Read the privacy policy.

- You leave home and you don't know
Today, a stable aquarium depends on you, a thermostat and a timer. The Core takes care of it right at the tank.
From sunrise to moonlight, without lifting a finger.
- 07:00
Sunrise
The light comes up slowly, just like outside. The curve has a value for each hour and the Core blends gently between them.
- 13:00
Feeding time
Tap Feeding: the filter pauses, three warm pulses of light call the fish and the feeding spot lights up. Afterwards, everything goes back to normal on its own.
- 17:30
Thunderstorm
Twenty seconds of lightning across the water. Schedule storms by the hour or start one with a tap in the app.
- 21:00
Sunset
The light turns warm and low until it fades out, at the time you chose. No sudden switch-off.
- 23:00
Moonlight
A faint blue light that follows the real phase of the moon, with stars and the occasional shooting star.
You choose the species. The Core does the rest, hour by hour, every day.
The internet drops. Your aquarium won’t notice.
The Core makes every decision right at the tank: temperature, light and equipment. The internet is only for seeing and changing things in the app.

Tell us who lives in the tank. The Core knows what they need.
Pick a few species and see the profile the app suggests. It’s the same catalogue the app uses.
Know everything’s fine without opening the app.
In plain words
It tells you what happened, what to check and when things are back to normal.
Safety first
If the water sensor stops reading, the Core switches the heater off after 10 minutes and lets you know.
In the app and by email
Maintenance reminders arrive at the right time too: mark them as done with a tap.

Do I need internet for the aquarium to work?
No. The Core controls water, light and equipment right at the tank. The internet is only for seeing and changing things in the app. When it comes back, the app catches up.
Which aquariums are compatible?
Freshwater aquariums, planted or not. Paludariums and terrariums come later.
Do I need to know electronics?
No. Plug in the Core, scan the QR code with your phone and pick your Wi-Fi. Your equipment plugs into the Power module like a regular power strip.
Can I use the equipment I already have?
Yes. Filter, heater, CO₂ and air pump plug into the Power module and start following the routine.
How much is it and when does it ship?
We're still finalising the price and date for the first batch. People on the waitlist hear first.
Can I have more than one aquarium?
Yes. Each setup has its own Core and you see them all in one account.
What comes in the system?
The Core, which measures water, air and humidity and decides what to switch on and when; the Power module, where you plug in your filter, heater, CO₂ and air pump; and the Light, with sunrise and sunset, clouds and moonlight.
What about mains power? Is it safe?
Mains power stays in the Power module. The Core and the sensors run at low voltage, and the Core only tells each socket to switch on or off.
What if the Core breaks?
The app lets you know if the Core stops responding. While we sort it out, you can plug the filter and heater straight into the wall, as before.
Does it work on iPhone and Android?
Yes. The app opens in your browser and installs on your home screen like a regular app, on iPhone and Android.
