Intelligence, built in
An AI that actually knows your tank.
AquaSense reads the parameters you log, identifies what's living in your tank, and flags trouble early — all from your phone. No tank camera required.
Ask your tank anything
The optional AI assistant sees your logged parameters and tank history — and answers in plain English, not jargon.
Photo ID for fish & coral
Snap a photo and get an identification with care notes, ideal parameters, and compatibility — straight from the species library.
Diagnose by photo
Point your camera at algae, a stressed fish, or cloudy water and get a likely cause with clear next steps.
Early-warning watchdog
AquaSense watches your parameter trends and warns you about slow drift before it becomes a crash.
Stocking & compatibility
Plan a tank, check who gets along, and size your bioload before you buy — so nothing ends up in the wrong tank.
Maintenance that remembers
Routines and reminders keep water changes, dosing, and tests on schedule — and keep a tidy log once you check them off.
Plenty of apps can log your tank. AquaSense actually helps you run it.
Early problem detection comes from the data you log — there's no tank camera to mount and no video subscription. Core tracking and reminders are always free; the AI assistant is an optional upgrade.
Everyday care
Everything a healthy tank needs, in one place.
Track every parameter
Log temperature, salinity, pH, alkalinity, and more — with clean charts that surface trends before they become problems.
Reminders that stick
Water changes, dosing, and tests on a schedule you set. AquaSense nudges you at the right time and logs it when you're done.
Multi-tank ready
Run a nano and a reef and a quarantine tank side by side — each with its own history, livestock, and routines.
Meet the AquaSense ATO — the zero-maintenance sump.
We're building the AquaSense ATO — an auto top-off that keeps your sump level rock-steady with strictly external, non-contact sensors. No optical sensors or float switches sitting in the water, so there's nothing to clean, foul, or stick. It isn't for sale yet — join the waitlist and you'll be the first to know when it ships.
- Strictly external, non-contact sensing — no optical sensors or float switches inside your sump
- Zero maintenance: nothing in the water to clean, calcify, or jam
- On-device failsafes that run even when Wi-Fi is down
- Pairs with the AquaSense app you already use
No spam — one email when it's ready to ship.
