Track Your Reef Tank Parameters Inside Your CoralBay Account

Good reef keeping is built on stability. Most reefers know this already, but keeping track of water parameters over time is not always as simple as it sounds.

A quick note on paper works for a while. A spreadsheet works too, if you remember where you saved it. But over time, readings can become scattered, forgotten, or difficult to compare. That is why CoralBay now includes a dedicated Tank Parameters section inside your account.
You can find it here:

My Account → Tank Parameters

or directly at:

A simple way to track what is happening in your reef

The new Tank Parameters area lets logged-in CoralBay users create their own tank logs, add the parameters they want to follow, and record readings over time.
Nothing is hard-coded. Every reef tank is different, so you decide what matters for your system.
You can create parameters such as:

  • Alkalinity
  • Calcium
  • Magnesium
  • Nitrate
  • Phosphate
  • pH
  • Salinity
  • Temperature
  • ORP
  • or anything else you want to monitor

For each parameter, you can set the unit and your own ideal range. For example, you may want calcium to sit between 400 and 450 ppm, nitrate between 5 and 25 ppm, or phosphate between 0.05 and 0.15 ppm. These ranges are yours to define and edit.

Multiple tanks, one account

Many reefers run more than one system. A main display tank, a frag tank, a nano tank, a quarantine tank, or a coral holding system may all have different targets and different readings.

CoralBay Tank Parameters supports multiple tanks from the start. You can create each tank separately and manage its readings independently.
This means your main reef and frag tank do not have to be mixed together in one confusing log. Each tank can have its own parameters, readings, graphs, and history.

Log readings quickly

The reading form is designed to be quick. Choose the tank, choose the parameter, enter the value, and save it. The date is automatically set to today, but you can edit it if you are entering older readings.
You can also add optional notes, such as:

  • water change done
  • adjusted dosing
  • new salt mix
  • tested after feeding
  • ICP correction started

These small notes can be very useful later when you are trying to understand why a parameter moved up or down.

See trends, not just numbers

A single test result only tells you what happened at that moment. A graph shows the trend.

Inside the Tank Parameters page, CoralBay displays your readings on a chart so you can quickly see whether a parameter is stable, rising, falling, or drifting out of range.
This is especially useful for reef tanks because many problems do not happen suddenly. Alkalinity, nutrients, calcium, magnesium, and salinity can slowly move over time. Seeing that movement visually makes it much easier to react before things become a bigger issue.

Ideal ranges shown clearly

When you create a parameter, you can set an ideal minimum and maximum value. These ranges are then used to help you understand whether the current trend looks healthy for your tank.
Instead of just seeing a number, you can compare the reading against the range you personally want for your system.
For example:

  • Calcium: ideal 400–450 ppm
  • Magnesium: ideal 1300–1500 ppm
  • Nitrate: ideal 5–25 ppm
  • Phosphate: ideal 0.05–0.15 ppm

This makes the data more meaningful. You are not just collecting numbers — you are building a picture of how stable your reef actually is.

All parameters overview

There is also an All params view, designed to give you a quick overview of your tank.

Instead of checking one parameter at a time, you can open a full overview and see your tank’s parameters together in a clear grid-style layout. This is useful when you want a quick health check of the whole system.
You can quickly see which parameters look stable and which ones may need attention.

Edit readings and fix mistakes

Everyone enters a wrong value occasionally. Maybe a decimal point is wrong, maybe the date is wrong, or maybe you want to add a note later.
CoralBay lets you edit saved readings. You can update the date, value, and note without needing to delete and re-enter everything.

You can also delete readings, parameters, or tanks if needed. When something is deleted, it is removed from the database rather than simply hidden.

Why not just use paper?

There is nothing wrong with a notebook. Many reefers have used paper logs for years. But paper has limits.
It can be lost, damaged, forgotten, or difficult to compare over time. It also does not show trends unless you manually draw them yourself.

A digital reef log gives you a cleaner view:

  • your readings stay inside your CoralBay account
  • you can access them when logged in
  • graphs are created automatically
  • ideal ranges are stored with each parameter
  • old readings remain available for comparison
  • you can see trends much more easily

For reef keeping, this matters. The goal is not to chase numbers every day, but to understand the direction your tank is moving in.

A useful tool for everyday reefers

This feature was built to be practical, not complicated. It is not designed to replace good reef keeping judgement, but to make it easier to stay organised.
If you are dosing two-part, adjusting nutrients, trying to stabilise alkalinity, monitoring a new tank, or simply trying to understand your reef better, keeping a proper record can help.

Over time, your tank log can show patterns that are easy to miss from memory alone.
For example, you may notice:

  • alkalinity drops faster as corals grow
  • nitrate rises after feeding changes
  • phosphate slowly increases before algae appears
  • calcium and magnesium drift after salt changes
  • salinity becomes less stable during warmer months

These are the kinds of small details that help reefers make better decisions.

Where to find it

The Tank Parameters tool is available to logged-in CoralBay users inside the account area.
Visit:

https://coralbay.uk/my-account/tank-parameters/

From there, you can create your first tank, add parameters, set your ideal ranges, and start logging readings.

If you are using a mobile phone, you can speed up access to your tank parameters dashboard by using “Add to Home Screen”. This creates a shortcut on your device, allowing much quicker access — similar to an app.

Better data, healthier reef

Reef keeping rewards consistency. The easier it is to track what is happening, the easier it becomes to keep things stable.
CoralBay Tank Parameters gives reefers a simple, private, account-based way to log readings, view trends, and understand their tanks more clearly.
Paper notes are easy to lose. Trends are harder to see in a notebook. With CoralBay, your reef data stays organised, visual, and easy to return to whenever you need it.

Stop guessing. Start tracking.
