Seachem 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. Calcium is vital for the calcification process of corals, clams, and other invertebrates. Unlike other calcium supplements, Reef Complete also includes magnesium and strontium in their natural relative ratios to ensure long-term ionic stability.
Reef Complete provides a bio-available source of calcium while ensuring the critical supporting minerals are present for skeletal development.
High Concentration: A powerful 160,000 mg/L formula, making it one of the most cost-effective liquid calcium supplements available.
Ionic Calcium: Delivered in a form that is immediately available for uptake by corals and calcifying organisms.
Balanced Formula: Includes magnesium and strontium to prevent the "precipitation" of calcium and support overall reef health.
pH Neutral: Specifically formulated to not impact the pH of your aquarium, allowing for independent management of alkalinity.
Easy Dosing: Ideal for maintaining calcium levels in tanks with moderate to high stony coral populations.
How much Reef Complete should I add? Use 5 mL (1 capful) per 80 L (20 US gallons) twice a week. It is recommended to check calcium levels with a test kit before and after dosing to adjust for your specific tank's consumption rate.
What is the target calcium level for a reef tank? Natural seawater is approximately 400 mg/L. Most reef hobbyists aim for a range between 380 and 450 mg/L to ensure optimal growth.
Can I mix this with Reef Carbonate? No. Like all calcium and carbonate supplements, they should be dosed at different times or in different areas of high flow to prevent them from reacting and precipitating out of the water.
Seachem Reef Carbonate: The perfect companion for managing alkalinity alongside your calcium dosing.
Seachem Reef Advantage Strontium: For high-demand systems that require additional strontium beyond what is provided in Reef Complete.
Seachem MultiTest Calcium: A high-precision test kit essential for monitoring your calcium levels and fine-tuning your dosing schedule.
