Reef Complete™ is a highly concentrated (160,000 mg/L) blend of ionic calcium formulated to restore and maintain calcium levels found in natural seawater without altering pH. Essential for all coral growth, calcium and carbonates must be kept in balance to ensure healthy coral development and prevent decline. This advanced formula delivers calcium alongside magnesium and strontium in precise ratios (100:5:0.1, Ca:Mg:Sr) to support optimal coral health and maintain these vital elements simultaneously.
To effectively use Reef Complete™, beginners should dose 1 capful (5 mL) per 80 L (20 gallons*) twice weekly, monitoring calcium levels every two weeks and adjusting as needed. More experienced aquarists can tailor dosing to maintain calcium within the ideal range of 380–420 mg/L, with each capful raising calcium by approximately 10 mg/L. It is important not to exceed 25 mg/L per day. Experts may implement a continuous drip system using a simple formula to calculate the precise amount to add to top-off water, ensuring consistent calcium supplementation.
For best results, avoid overdosing as excess calcium can accelerate carbonate alkalinity loss. Do not mix directly with carbonate supplements; instead, alternate dosing days or allow at least 30 minutes between additions. When used alongside complementary carbonate products, maintaining calcium levels below 400 mg/L is recommended. Regular monitoring with Reef Status™: Calcium test kits helps ensure optimal water chemistry.
This carefully balanced conditioning solution is ideal for saltwater reef and marine aquariums, supporting vibrant coral growth and overall reef ecosystem health. Trust this scientifically optimized formula to provide essential minerals that mimic natural seawater conditions, enhancing your aquatic environment with precision and ease.
