Reef Trak 2.3.1 Changelog: A Safer, Smarter Guided Dosing

Published June 23, 2026. Reef Trak 2.3.1 is mostly a Guided Dosing update, but it is a big one. The dosing engine was rebuilt to make recommendations safer, clearer, and better tied into the science behind your reef.

A small-looking update with a big rebuild inside

Reef Trak 2.3.1 may look like a minor release from the outside, but most of the work happened where you cannot see it: inside the Guided Dosing engine. Dosing is the one place in a reef app where a wrong number does real harm, so the whole engine was rebuilt around a simple principle — be safe first, be clear second, and never pretend to know more than the data supports.

If you use Guided Dosing, the recommendations you get now are more conservative in the right moments, more transparent about why, and better connected to the rest of the app.

Safer recommendations by design

The biggest change is how the engine decides what to suggest. Instead of pushing a parameter toward the edge of its acceptable range, Guided Dosing now aims for the middle of your safe range when that is the right move, which leaves a margin for error instead of riding a limit.

Aims for the middle of your safe range, not the edge of a limit
Smarter HOLD, PAUSE, and STOP logic when a dose may be unsafe
Checks every parameter a product can affect, not just the main one
Better handling for concentrated products, especially on smaller tanks
Multi-dose schedules now split the daily dose correctly instead of repeating the full amount

Honest about what it knows

Manufacturer data is not always complete, and the engine no longer hides that. Reef Trak 2.3.1 adds confidence and data-quality messaging, so when product information is incomplete the app tells you, rather than presenting a shaky number as if it were certain.

When dosing is paused or held, you now get a clear reason on the card instead of a blank status area. A new Guided Dosing onboarding flow explains how the system works the first time you reach it, and Dosing Guidance is now included in TrakAI exports so the assistant has the full picture.

Fixed dosing cards flickering between paused and active states
Fixed cases where reducers could keep suggesting dosing at or below the safe floor
Fixed monitor-only products so they no longer look like active guided recommendations
Improved dosing updates when new parameter readings are saved
Fixed an issue where updating a fish could wipe the fish photo
Added a flexible "Every N months" maintenance recurrence
Improved parameter alert averages and trends
Hardened premium gating and cleaned up old app logic

Final note

Reef Trak 2.3.1 is mostly a dosing update, but it is a big one. Guided Dosing is now safer, smarter, clearer, and better tied into the science behind your reef. As always, if something does not look right, please send a bug report so it can be fixed quickly. Love Your Reef, Trak it.

Frequently asked

What is new in Reef Trak 2.3.1?

Version 2.3.1 rebuilds the Guided Dosing engine for safety and clarity. Dosing now aims for the middle of your safe range instead of the edge of a limit, adds smarter HOLD/PAUSE/STOP logic, checks every parameter a product can affect, splits multi-dose schedules correctly, and adds confidence and data-quality messaging. It also adds Guided Dosing onboarding, Dosing Guidance in TrakAI exports, a flexible "Every N months" maintenance recurrence, improved parameter alert averages and trends, and several fixes.

Did Reef Trak change how dosing amounts are calculated?

Yes. The Guided Dosing engine now targets the middle of your safe parameter range when appropriate rather than the edge of a limit, leaving a safety margin. It also checks every parameter a product can affect (not just the primary one), handles concentrated products and small tanks more carefully, and splits multi-dose-per-day schedules so the daily total is divided across doses instead of repeated.

Why does Guided Dosing sometimes hold or pause now?

When a dose could push a parameter past a safe limit, or when product data is incomplete, Reef Trak now holds or pauses the recommendation and shows you the reason on the card. This is intentional: the engine is designed to be conservative when safety is uncertain, and to be transparent about why rather than presenting a shaky number as certain.

Is my reef data affected by this update?

No. Reef Trak 2.3.1 is a logic and interface update with no database schema change, so your tanks, parameters, dosing schedules, livestock, and history carry over untouched. The changes affect how dosing recommendations are calculated and explained, not your stored data.
