TRI-DOSE
Just One Dose for Reef Balance

Why use tri-dose

Reef tanks thrive on stability — but juggling calcium, magnesium, and alkalinity dosing can feel like a full-time job.
Tri-Dose takes the stress out of reef chemistry by delivering all three in one perfectly balanced, easy-to-use formula.

Whether you’re growing SPS, LPS, or softies, Tri-Dose keeps your parameters steady and your corals smiling.

Calcium
The Coral Builder

Calcium

What it does: Calcium is the backbone of coral growth. Literally. Corals use calcium to build their skeletons.

What happens if it’s off?

Too low: Corals slow down or stop growing.

Too high: Can lead to precipitation (snowstorm effect) and imbalance with other elements.

Magnesium
The Hidden Hero

Ref image

What it does: Magnesium helps keep calcium and KH from reacting with each other. It’s like the referee in your tank — keeps the peace.

What happens if it’s off?

Low magnesium = unstable calcium and alkalinity levels.

High magnesium can impact invertebrates and encourage algae growth.

Alkalinity (KH)
The pH Buffer

KH and pH Stability Graph

What it does: KH (carbonate hardness) keeps your pH stable, which is vital for coral health and metabolic function.

What happens if it’s off?

Low KH = pH swings, stressed corals.

High KH = possible burnt tips or unwanted precipitation.

It’s All About Balance

These three work together. You can’t just raise one and hope for the best — they’re part of a system.

Like trying to ride a tricycle with one wheel too small — you’ll wobble and crash.

Too often, reefers get stuck in the dosing juggle, tweaking one parameter and accidentally throwing another out of whack.

The Smart Way: Tri-Dose

That’s why we made Tri-Dose – Just One Dose for Reef Balance.

✅ Balanced Calcium, Magnesium & KH
✅ One simple dose
✅ No guessing
✅ Designed for reefers who want consistent results with less hassle

Whether you’re a seasoned reefer or just starting out, keeping your parameters stable shouldn’t be a chemistry exam. Tri-Dose gives your corals what they need, without the extra stress on you.

How to Use

Shake well before use.
Start with no more than 3ml per 100L Daily 
Use the sullied dosage cup or, preferably, an autodoser.

 

Dosage Instructions:

Shake well before use.
DOSE 5ml per 100 Litres of aquarium water daily.

To achieve a stable Kh
Test 5-7 days in a row and record the results to work out the average daily Kh usage.
Adjust the dose every 2-3 days after testing no more than 2ml daily.
Wait 2-3 days and test again before adjusting again.

2ml will raise Kh
0.6 in a 100L Aquarium
0.3 in a 200L Aquarium
0.15 in a 400L Aquarium

 

Take your time and test regularly!!
Overdosing or large adjustments could kill fish and corals.

Recommended Testing

Regularly test your Ca / Mg / KH to ensure optimal levels:

Calcium: 400–450 ppm

Magnesium: 1280–1350 ppm

KH: 7–9 dKH

KH being the most important as it can change the quickest.

Tri-Dose Reviews

“I’ve been using Tri-Dose for about 2 months now and it’s made a huge difference. I’m currently dosing 7ml per day in my 120L mixed reef and it’s keeping KH stable at 8.1, calcium around 430, and magnesium at 1320. Corals are noticeably happier — polyp extension is better and colours are popping more. Love not having to juggle 3 bottles anymore!”

Mark J. – Bristol, UK

“Brilliant product. I’ve got a small SPS-dominated nano (90L) and dosing just 5ml a day of Tri-Dose. It’s holding parameters rock solid: KH 8.3, Ca 440, Mg 1340. Super easy to use, and I’ve definitely noticed more consistent growth. Highly recommend for anyone tired of overcomplicating reef dosing!”
