Red Sea Salt Mix for 55-Gallon Aquarium
Natural seawater contains more than seventy chemical elements, but only a few play a vital role in maintaining chemical balance and reef health. Among these, calcium, magnesium, and bicarbonates are the key foundation elements. They directly influence water chemistry—such as pH stability, alkalinity, and ionic strength—and are essential for coral functions like skeleton building, ion exchange, and photosynthesis.
In contrast to the ocean, a reef aquarium holds only limited amounts of these critical elements, which are quickly consumed by corals and other inhabitants. To support sustainable coral growth, aquarists must maintain levels of these elements even higher than those found in nature.
| Element | Recommended Level (ppm) |
|---|---|
| Calcium | 400 – 450 |
| Magnesium | 1250 – 1350 |
| Bicarbonate | 75 – 85 |

The salt mix has made a noticeable difference in my reef tank. My corals are growing stronger and the water chemistry has stabilized after a few weeks. Easy to mix and consistent in performance.
Leah Dowd –
I’ve used this salt mix for three months now and the pH and alkalinity levels have stayed steady. My polyps are more active and the tank looks healthier overall.

Great product for maintaining balanced water parameters. The calcium and magnesium levels are well within the recommended range. I don’t have to adjust my water frequently anymore.
