Every tank has a story.
Let's read yours.

An aquarium assistant that actually knows your tank. Its size, its age, its livestock, its last water test.

What it actually does

You build your tank once. From then on, everything you log makes the answers sharper.

🐠

Keeps your tanks

Every system you run: size, sump, age, equipment, filter media, and every fish, coral, plant and invert in it. Add as many tanks as you keep. Each one is remembered separately.

🧪

Tracks your water

Log a test in seconds and watch it over time. Ammonia, nitrite, nitrate, phosphate, alkalinity, calcium, magnesium, salinity, pH, temperature. Water changes and your RO/DI filters too.

💬

Triggy learns your tank

Triggy runs on Claude. He doesn't answer in general. He answers with your gallons, your livestock, your last test in front of him. A 12-gallon nano and a 200-gallon predator system get different answers to the same question.

📚

Fish health, from real sources

Health guidance is restricted to peer-reviewed aquatic-veterinary literature and established fish-health references. No forum myths, no folk remedies, no random website that happened to rank first.

🚫

Never invents anything

If he doesn't know, he says so. He won't guess a diagnosis from a blurry photo, he won't fabricate a source, and he will never give you a dosage. Two bottles of the same medication can differ tenfold. Read the label in your hand.

🩺

Reads the tank before the fish

A gasping fish is usually a water problem, not a disease. Triggy checks your parameters before he reaches for a medication, because half of what looks like illness is chemistry.

Live camera

TANKSENSE shows a live feed of your tank on your phone, from anywhere. It works over cellular, from outside the house.

It uses a supported Reolink camera on your own network. Setup is a QR code: you scan the code printed on the camera and the app puts it on your Wi-Fi. There is no Reolink app to install and no Reolink cloud account.

  • Pan, tilt and zoom from the same screen.
  • One camera per tank.
  • Private camera credentials are encrypted in your account and cached in the device secure store.

The TANKSENSE camera, showing six colour presets for different aquarium lighting and a strength slider

We built our own camera

Aquarium lights lie about colour. Blue actinic turns a phone photo into a purple mess, and plant LEDs lay a magenta cast over everything green.

So TANKSENSE has its own camera, with six colour presets matched to what is actually over your tank: white daylight, planted, the standard 50/50 reef look, heavy actinic, true colour, and a vivid one for showing off. The correction runs on the live preview, so you see the real colours before you take the shot, and a slider sets how hard it works.

You set the shutter yourself, and each option says what it is for: auto, 1/125 for more light, 1/250 for moving fish, 1/500 for fast fish, 1/1000 for very bright tanks. It is a ceiling rather than a fixed setting, so the camera keeps metering and buys the light back with ISO. A tang crossing the glass at 1/30 is a smear, and a grainy sharp photo of white spots can be diagnosed where a clean blurred one cannot.

If there is not enough light for the shutter you picked, it tells you so on screen rather than quietly handing you a dark photo.

There is no flash and no torch, ever. It bounces off the glass, and it startles an animal that is already unwell.

When you take the shot, you either save it to your camera roll or hand it straight to Triggy without leaving the screen.

  • Ask Triggy about coral health and the vivid preset is taken off the table. Saturation can make a dying Acropora look fine.
  • Shutter, exposure, zoom, a grid and a level, all on the same screen.
  • Hold the shutter for a burst, or switch to video.

Parameter charts

Any parameter you log, plotted over time, with its acceptable range shaded behind the readings. No trend lines and no projections. The chart stops at your last reading. Charts can be shared as an image.

📄

ICP reports

Scan an ICP report and the values are read off it and stored against your tank, so one report can be compared to the next. Every value is shown to you to check first. Nothing is saved until you say so.

🧾

Receipt scanning

Photograph a receipt from the shop and the livestock is added, with the date you bought it. Shop shorthand is expanded into species names. You review the list before anything is added.

🚰

RO/DI tracking

Log your TDS readings and the app estimates the life left in each filter stage, so you replace media before it fails rather than after. Carbon is tracked by date instead, because chlorine does not show up on a TDS meter.

Why this exists

His name was Rocky. A clownfish, living in a sea anemone, in my parents' saltwater tank. We had a freshwater tank too, but Rocky is the one I remember. I was a kid, and I could not work out why the anemone wasn't stinging him. Two animals with nothing in common, one of them covered in weapons, and they'd decided to look after each other. I was mesmerised. I've never really stopped being mesmerised.

Our tanks grew. In high school I worked at an aquarium shop in New Jersey called Ocean Aquarium, where I met one of my best friends and where the hobby properly got its hooks into me. In college I still had tanks; a 20 high was a favourite, and then the classic 55. I'm still in it today. Two reef tanks.

In all that time, what I keep seeing is people losing animals they could have kept. Copper dosed into a tank full of shrimp. Ich treated when it was velvet. A dose taken from a stranger on a forum who had never seen the tank. The fish didn't die because the hobby is hard. They died because the information was wrong.

Meanwhile the local fish stores, the ones with somebody behind the counter who actually knew things, keep closing. What's left is the open internet, and for fish health that is the wild west.

So TANKSENSE is my attempt to put the good counter back. Triggy runs on Claude, but the part that matters is what I built around it: he's held to vetted aquatic-veterinary sources for anything to do with fish health, he's given your actual tank to reason about, and he is hard-stopped from the things that kill fish. He will never give you a dose, and he will never tell you to do something drastic. When he doesn't know, he says so.

My goal is simple. Help people love and care for their aquariums, any size, any type, and give something back to a hobby that has given me most of my life. I'm here to save fish.

I've got a few other ideas up my sleeve, too.
