Seachem Reef Pack Fundamentals
Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. To prevent this you must provide calcium (Reef Complete) and carbonates (Reef Carbonate). To improve vitality and overall health of the corals (which in turn accelerates growth), provide vitamins, amino acids and trace elements with Reef Plus. Reef Pack Fundamentals combines these three products in this foundational pack perfect for beginners.
Reef Complete
Reef Complete is a concentrated (160,000 mg/L) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater without affecting pH. Reef Complete also includes magnesium and strontium in amounts proportionate to typical seawater levels.
Reef Carbonate
Reef Carbonate provides essential carbonate ions to support coral growth and maintain stable water chemistry. It helps balance the alkalinity of the tank and ensures adequate carbonate levels for healthy coral development.
Reef Plus
Reef Plus delivers vitamins, amino acids, and trace elements necessary for coral vitality and overall health. These nutrients support metabolic functions and promote faster growth and coloration in corals.

| Reef Complete | Calcium, magnesium, strontium | Maintains calcium and magnesium levels without affecting pH |
| Reef Carbonate | Carbonate ions | Supports coral growth and stabilizes alkalinity |

I just started my reef tank and this pack made a big difference. The corals are growing steadily and look more vibrant than before. Easy to mix and the instructions are clear. Great for new hobbyists.
Carolyn Gill –
After using the Reef Pack Fundamentals for two months, my polyps are more active and the coloration has improved. The calcium and carbonate levels stayed stable, which I was worried about at first.
Bernadette Murray –
The product works well, and the combination of all three components is convenient. I still need to monitor alkalinity occasionally, but overall it’s a solid starting point for a new reef setup.
Lauren Lyman –
As a first-time reef owner, I was nervous about water chemistry. This pack gave me confidence. My corals are thriving, and the growth has been noticeable in just a few weeks.
Kylie Henderson –
The Reef Complete and Reef Plus are easy to use. I found the carbonate dosage a bit high at first, but after adjusting, it’s working well. Would recommend for beginners.
