Improved

Export your whole tank to Excel

Tank settings, Export now gives you the whole tank in one Excel file: every reading (it used to stop at the newest 10,000, which a probe fills in a few weeks), every dose and water change, plus your journal, ICP results and quarantine logs. Times are on your own clock, temperatures and volumes are in your tank's units, and each salinity has its S.G. beside it. Photos and videos stay in the app. Yours to keep, back up or share.

Improved

A simpler app for one hand

TankSensei is easier to use with one hand. A tank's Home now starts with Today, with what needs you first (unless you arranged Home yourself), and each test is one line: tap it to open its card. A test reading high or low opens by itself. The bar at the bottom is now Home, Log, Tasks, Tank and Near. Log is where you record anything you did at the tank: a test, a water change, a dose, a note with photos, a follow-up. Tank holds the rest: supplies, dosing, equipment and devices, livestock, the journal, history, ICP results and settings. Account has a page of its own.

New Asked for by a reefer

Bring in your past tests from a spreadsheet

Kept your tests in a spreadsheet? Bring them into a tank's history: a CSV or Excel file, or rows pasted from Google Sheets. You check each column and its unit (dKH or meq/L, ppm or ppb, °F or °C, S.G. or ppt) before anything is saved, and a number no test kit could read is shown and left out. Imported tests fill your charts but send no alerts, and you can remove the whole import later. Find it under Import tests on Home, or in Log.

New

Connect HYDROS with a key, no password

Connect your HYDROS with a key from the HYDROS app instead of your CoralVue password. TankSensei only reads with it: temperature, pH, salinity and alkalinity are recorded, ORP is kept as history, and your probes show on a live tile on Home. One key covers a whole Collective; if it runs more than one of your tanks, TankSensei asks which probes belong to each. Connected with your password before? That keeps working for now. Step by step, with screenshots: tanksensei.com/hydros

Every test on one page, and any dose

Tap All history on Home to see every parameter's chart on one page, in your own units, with how far each sits from target. On Log, Dose records anything you add: trace elements, iodine, nitrate, any brand, in mL, drops or grams. The tank owner can also add their own alkalinity, calcium or magnesium product to the calculator: type the strength from its label and it does the math, with the same daily safety limits.

Online reef stores in Near You

Near You now lists online reef stores beside your local ones: tap Online to see where each one ships and what they sell, with a link to their shop. In the US, Canada, the UK, the EU, Australia and New Zealand, the ones that ship to you come first. Know a good one we are missing? Tap + Online store, add its website and where it ships, and we will check it before it goes live.

New

Quarantine tanks and treatment log

Add a tank as a quarantine or hospital tank: only temperature, ammonia, nitrite and pH are graded there, so hyposalinity is not called low, and it gets ammonia and nitrite cards and no reef chores. Start a quarantine or treatment from the Tank tab: it counts the days, reminds you to check in and keeps your log of observations, doses, tests and water changes, with photos. Fish in one are marked on Home and keep the log in their history. Doses come from the product label: TankSensei never suggests a medication or a dose, and warns before copper goes into a tank with corals or inverts.

Keep a record of every coral and fish

Add dated notes to any coral or fish from its card, and they show in the tank journal too. When one leaves the tank, mark it died, lost, rehomed or something else, with a date and a note in your own words. It stays on a new History page with its photos, notes, how long you kept it and your readings from the week before. Nicknames tell two of the same species apart, you can record a frag you took, and deleting a tank asks whether to keep this history.

New

Log readings and check your tank with Siri

Set up an iPhone Shortcut to log a reading by voice; Siri reads back what it heard and only saves once you confirm. You can also ask for a spoken summary of your tank, and the setup guide lives at tanksensei.com/siri.

New

ICP results page and more labs

Each ICP test has its own page: what changed since your last test, a trend chart per element, and after two tests, how fast your tank uses alk, calcium and magnesium. Import ATI from its PDF, CSV or share link, plus Triton, Oceamo and Tropic Marin CSV exports and Reef Labs spreadsheets. PDF uploads keep the original file, and trace elements reported in µg/L are judged in the right unit.

Plus seven smaller improvements and fixes.

Log water changes and keep a tank journal

Log a water change in one tap, with the salt drawn from your supply and mixing amounts for your brand. A Journal section on Home lists your water changes, doses, additions, photos and ICP imports in order, plus your own notes.

New Asked for by a reefer

Track supplies that count themselves down

Log salt, additives and test kits, and they draw down as you dose, change water or run tests, with a learned daily use and reorder links.
