Seachem Reef Complete 250ml

Seachem Reef Complete

Seachem Reef Complete is a concentrated liquid ionic calcium supplement for marine and reef aquariums, formulated for aquarists maintaining calcium for coral growth. This 250 ml (8.5 fl oz) Seachem marine conditioner provides calcium alongside magnesium and strontium in proportions based on typical utilisation ratios.

Key Benefits

• Contains 160,000 mg/L calcium in a fully soluble liquid formula.
• Designed to restore and maintain calcium at levels found in natural seawater without affecting pH.
• Includes magnesium and strontium in a 100:5:0.1 calcium-to-magnesium-to-strontium ratio.
• Blended at a higher pH to allow ammonia to gas off into the atmosphere.
• Supports calcium supplementation alongside carbonate additives, which are both essential for coral growth.

Dosage

• Beginner: Add 1 capful (5 mL) per 80 L (20 US gallons) twice weekly. Check calcium every two weeks and adjust the amount or frequency as required.
• Advanced: Use the same addition regimen until calcium reaches 380–420 mg/L. Each 5 mL per 80 L (20 US gallons) raises calcium by approximately 10 mg/L.
• Do not exceed 12.5 mL per 80 L (20 US gallons) per day.
• Expert continuous dosing: m=vc/160, where m is mL of product for top-off water, v is aquarium volume in litres, and c is the desired calcium increase in mg/L.

Compatibility

Do not directly mix Reef Complete with any carbonate supplement; add calcium and carbonate products on alternate days or at least 30 minutes apart. When using with Reef Calcium™, it is not necessary to exceed 380 mg/L total calcium.
