Seachem Reef Trace Reef Aquarium Trace Element Supplement, 4 L, Nitrate- and Phosphate-Free

Seachem Reef Trace is a 4 L (1 fl. gal.) trace element supplement for reef aquariums, formulated to replenish a broad range of elements necessary for reef health and growth.

• Broad range of trace elements — helps restore elements used by reef life.
• 4 L (1 fl. gal.) container — provides a large-format supply for regular replenishment.
• May be used alone or with Reef Plus — fits either approach to trace element supplementation.
• Nitrate- and phosphate-free formula — supplies trace elements without adding either of these nutrients.
• Guaranteed analysis for nine trace elements — gives the amount of each element per gram.

Trace elements in a reef aquarium are depleted through utilization, oxidation and precipitation. Oxidation and precipitation can reduce them more quickly than other micronutrients, so regular replenishment matters. Reef Trace is made for aquarists who want to add a broad range of trace elements as part of reef care, whether using it on its own or alongside Reef Plus.

What is Seachem Reef Trace designed to do?

Seachem Reef Trace supplies trace elements demonstrated to be necessary for proper reef health and growth. Its purpose is to replace elements that are gradually depleted, including through oxidation and precipitation, which occur more rapidly than with other micronutrients. This makes it suited to routine trace element replenishment rather than a one-time addition.

• Supplies a broad range of trace elements.
• Addresses depletion through utilization, oxidation and precipitation.
• Made for use in reef aquariums.

Can Reef Trace be used by itself or with Reef Plus?

Seachem Reef Trace may be used alone or in conjunction with Reef Plus, and the brand identifies use of both as the approach that gives the best results. The two-product option lets reef keepers pair Reef Trace with Reef Plus as part of their supplementation routine. Reef Trace itself is nitrate- and phosphate-free.

• Use Reef Trace alone or alongside Reef Plus.
• Best results are obtained when both products are used.
• The Reef Trace formula is free of nitrate and phosphate.
