FAQ

Do I really need to dose calcium, alkalinity and magnesium?

If you’re keeping corals — especially SPS — yes. Corals consume these daily, and without dosing, levels drop fast, leading to poor growth and instability.

How do I know how much 3 Part to dose?

Start by testing your tank daily for a few days. Once you see how much your levels drop, you match your dosing to that consumption. After that, it becomes very consistent.

Can I overdose Coral Essentials 3 Part?

Yes — like anything. Overdosing can push parameters too high and stress corals. The key is stability, not chasing high numbers.

Will Coral Essentials improve coral colour?

Yes — but colour comes from a combination of stability, lighting, and nutrition. Coral Essentials supports all of that, especially with Amino/Gro and CVE.

Can I use Coral Essentials with any lighting system?

Absolutely. It works alongside any lighting — it’s about supporting the coral’s internal health, not replacing lighting.

Do I need to use the full range or just the 3 Part?

You can run just the 3 Part for stability, but the full range is designed to work together — giving you better growth, health, and colour over time.

What’s the biggest mistake people make with dosing?

Inconsistency. Changing doses too often or chasing numbers instead of keeping things stable is what causes problems.

Complete Daily Supplementation For Healthy Reef Aquariums

Coral Essentials Calcium, Alkalinity & Magnesium + Traces combines the three major elements with carefully selected trace elements in convenient ready-to-use liquid supplements. Designed for consistent daily dosing, each solution helps replace what is naturally consumed, making it easier to maintain stable water chemistry and support long-term reef health.

Growing and Farming Coral For Over 20 Years.

The Coral Essentials system came out of years of trial, error, losses, and refinement on a real working coral farm — not a lab, not theory, but day-in, day-out testing on tanks packed with demanding SPS.

Every element in the 3 Part + Trace was dialled in to do one thing: keep parameters stable, predictable, and repeatable. Not just calcium, alkalinity and magnesium in isolation, but how they actually behave together in a living system over time.

What you get as a reefer is that same consistency — stronger growth, better colour, and fewer swings. No guessing, no chasing numbers. Just a system that’s been proven where it matters most: in real tanks, growing real coral.

Grow Frags into Lifelong Colonies

A proper reef isn’t built in stages — it’s supported the whole way through. The Coral Essentials range is designed as a full system, from your first frag right through to fully grown colonies.

It starts with the foundation: the 3 Part + Trace, keeping calcium, alkalinity and magnesium stable so everything has the base it needs to grow properly.

From there, Amino and Gro step in — delivering amino acids, fatty acids and essential vitamins that fuel tissue development, health and steady growth. Then once your tank matures and your corals are established.

CVE takes it to the next level — driving feeding response, enhancing colour, and pushing that extra vibrancy with a blend rich in B vitamins.

It’s not random bottles — it’s a complete reef care system, built to work together, the same way we’ve run it on coral farms for years. From frag to colony… it’s all covered.

Complete Reef Care From Just $0.11 Per Day

Tailored for tanks up to 100 litres (25 gallons), whether you run a soft coral, mixed reef, or full SPS system — Coral Essentials is your perfect match.

From just $0.11 per day for Soft Coral/LPS, $0.23 per day for Mixed Reef, and $0.76 per day for Full SPS, you get precise, reliable dosing to suit your tank’s needs.

How do we do it? By crafting ultra-concentrated formulas that deliver maximum performance with minimal waste.

Cost-effectiveness meets concentrated excellence.

Coral Essentials Calcium, Alkalinity & Magnesium

The Foundation Of Stable Reef Chemistry

Every thriving reef aquarium is built on stable water parameters. As corals, coralline algae and other calcifying organisms grow, they continuously consume calcium, alkalinity and magnesium from the water. Replacing these essential elements consistently is one of the most important aspects of long-term reef success.

Coral Essentials Calcium, Alkalinity & Magnesium provides convenient ready-to-use supplementation designed to help maintain these critical parameters. Whether dosed manually or through an automated dosing system, the balanced liquid formulation makes it simple to replace what growing reef organisms consume each day.

The result is greater stability, simplified maintenance and a stronger foundation for healthy coral growth.

Replace Essential Elements Daily

Reef aquariums are constantly changing.

Every day, corals use calcium and carbonate to build skeletal structure, while magnesium helps maintain the balance and availability of these critical elements within the system. Without regular replenishment, parameter stability can gradually decline as coral demand increases.

Consistent supplementation helps maintain the stable conditions that healthy reef aquariums rely upon.

Simple, Ready-To-Use Dosing

Maintaining a reef should be predictable and straightforward.

The ready-to-use liquid format eliminates mixing and preparation, allowing hobbyists to begin dosing immediately. Suitable for manual dosing schedules or automated dosing pumps, it provides flexibility for both beginner reef keepers and advanced coral systems.

As coral growth increases, dosing can be adjusted to match the evolving needs of the aquarium.

Customer photo review of Coral Essentials 2 Part + Magnesium and Traces 2.75L

Great product, superior to Red Sea as you can replace each individual element as they deplete from you system. And replace the bottles individually, saving money and on waste of unused elements.
