Red Sea Foundation Supplements Complete Pack

The Red Sea Foundation Supplements Complete Pack delivers the three essential building-blocks your reef tank constantly depletes: calcium, carbonate/alkalinity, and magnesium. When corals grow and build skeletons, these foundation elements are consumed — this pack replenishes them reliably to support healthy growth, stable pH, and strong skeleton formation in corals and invertebrates.

Each component is formulated to maintain a balanced ionic composition, avoiding imbalances that can occur with ad-hoc dosing. When used in combination with regular testing (e.g. with a KH/Ca/Mg test kit), dosing can be tailored to actual uptake — helping you avoid wastage while keeping water chemistry stable.

Typical dosing effect: 1 ml per 100 L raises calcium by ~2 ppm, alkalinity by ~0.1 dKH, and magnesium by ~1 ppm. 

This pack is ideal for reef-keepers who want a straightforward, reliable way to maintain foundational seawater chemistry without juggling multiple supplements — especially beneficial for mixed reefs and SPS/LPS setups.
