Red Sea Reef Foundation A is a concentrated supplement designed to maintain optimal levels of calcium, strontium, and barium in reef aquariums. These elements are essential for coral skeleton formation, supporting steady growth and long-term stability within marine systems.

Key Features:

• Contains calcium, strontium, and barium in natural reef ratios
• Supports coral skeleton development (skeletogenesis)
• Promotes efficient uptake of elements through coral tissue
• Helps maintain balanced foundation element levels
• Suitable for a wide range of reef aquariums
• Works as part of the Red Sea Reef Foundation Programme
• Dosage guide: 1ml raises calcium by 2ppm per 100 litres

Maintaining the correct balance of foundation elements is essential in closed aquarium systems, where natural replenishment does not occur. Elevated and balanced levels can support faster coral growth by reducing the energy required for element uptake, while lower levels may be preferred in mature systems focused on colour enhancement and nutrient control.

A reliable solution for reef keepers, Red Sea Reef Foundation A helps maintain stable water chemistry and supports healthy coral development.
