Seachem Reef Plus – Vitamin & Amino Acid Reef Supplement

Fuel Explosive Coral Growth and Eye-Popping Color

Aquarium water rarely carries the vitamins and amino acids corals get in the wild, and without them growth stays sluggish and colors stay dull.

Reef Plus is a comprehensive reef supplement for complex reef aquariums, packed with essential trace elements, broad-spectrum vitamins, and amino acids shown to improve the health of fish and invertebrates while driving explosive coral growth and vivid coloration. It replicates natural reef water with nutrients like Vitamin B12, Vitamin C, thiamine, inositol, choline, and iodide — and it's nitrate and phosphate free.

Reef Plus is developed by Seachem Laboratories, a science-driven chemistry company founded in 1979 in Madison, Georgia, where formulas are created in-house by chemists. That expertise is what lets Reef Plus combine trace elements, vitamins, and amino acids into a single nitrate- and phosphate-free supplement that mimics natural reef water. It is designed to work as the nutrition-and-vitamin component of Seachem's coordinated reef system, complementing the line's calcium, alkalinity, magnesium, and trace-element supplements so corals get both the minerals and the nutrients they need.

1. Use 1 capful (5 mL) for every 20 gallons of aquarium water twice a week, or as required for coral growth.
2. To target feeding, mix 1 mL of Reef Plus with 15 mL of food.
3. Add directly to the aquarium with no nitrate or phosphate worries.

Why Seachem Reef Plus

• Vitamin and amino-acid nutrition: supplies broad-spectrum vitamins and amino acids shown to improve fish and invertebrate health while driving coral growth and coloration.
• Replicates natural reef water: provides nutrients found in wild reef environments such as Vitamin B12, Vitamin C, thiamine, inositol, choline, and iodide.
• Nitrate and phosphate free: feeds the reef without adding the nutrients that fuel nuisance algae, so it can be dosed directly to the tank.
• Part of Seachem's reef system: complements the calcium, alkalinity, magnesium, and trace-element supplements to round out coral nutrition.

Best For

Complex reef aquariums keeping SPS, LPS, and soft corals plus fish and invertebrates, where vitamins and amino acids support vivid coloration and rapid growth — and where nitrate/phosphate-free feeding matters for water quality.
