Red Sea Reef Care Calcium+ Foundation A is a premium supplement formulated to maintain and regulate calcium levels in reef aquariums. Calcium is a critical building block for corals, as it directly supports the formation of their skeletons and overall structural integrity. Part of Red Sea’s Foundation Series, this product ensures a stable, well-balanced environment for optimal coral calcification, making it especially valuable for aquariums with SPS corals and other calcium-demanding species.
Supports Coral Growth – Supplies essential calcium for strong skeletal formation, crucial for SPS corals and other calcifying organisms.
Enhanced Formula – Enriched with trace elements to promote balanced mineral supplementation.
Concentrated & Easy to Dose – Precise dosing helps maintain stability without risk of overdosing.
Reef-Safe – Safe for all aquarium inhabitants, including fish, corals, and invertebrates.
Ideal for High-Demand Systems – Perfect for tanks with calcium-hungry corals requiring consistent levels for healthy growth and coloration.
Dosage:
Add 10g per 100L (26 gal) of aquarium water.
Use the included measuring spoon for accuracy.
Frequency:
For initial adjustments: Dose daily until calcium reaches the target range (400–450 mg/L).
For maintenance: Reduce to weekly or adjust based on your reef’s calcium consumption.
Application:
Dissolve the required amount in a small container of aquarium water before adding.
Add near the water intake or high-flow area to ensure even distribution.
Monitoring:
Test calcium levels regularly with a reliable reef test kit to fine-tune dosing.
1KG – Sufficient for medium to large reef aquariums, providing long-term supplementation.
For Calcium-Hungry Corals: Especially beneficial for SPS-dominant tanks.
Balanced Supplementation: Use alongside Foundation B (KH/Alkalinity) and Foundation C (Magnesium) to maintain complete reef chemistry stability.
Routine Monitoring: Regular testing ensures parameters remain within the ideal range for coral health and growth.
