Seachem Flourish Trace provides a broad range of trace elements demonstrated to be necessary for proper aquatic plant health and growth. In a closed aquarium system, trace elements are rapidly depleted through utilization, oxidation, and precipitation. Flourish Trace allows for the frequent replenishment of these vital micro-nutrients without the risk of over-accumulating the macro-nutrients found in a broad-spectrum fertilizer.
Flourish Trace is specifically engineered to address the "hidden" mineral needs of high-tech and low-tech planted tanks.
Comprehensive Trace Profile: Contains a scientifically balanced blend of boron, cobalt, copper, manganese, molybdenum, and zinc.
Prevents Nutrient Deficiencies: Regularly adding trace elements prevents common issues like "stunting," leaf distortion, and chlorosis (yellowing) in sensitive plant species.
High Bio-Availability: Minerals are provided in a form that is immediately accessible for absorption through both plant leaves and root systems.
No Macro-Nutrient Overload: Does not contain nitrogen ($N$), phosphorus ($P$), or potassium ($K$), allowing you to maintain micro-nutrients without causing an algae-triggering spike in macros.
Safe for Invertebrates: Formulated to be completely safe for all aquarium inhabitants, including sensitive ornamental shrimp and snails.
How is Flourish Trace different from Seachem Flourish?
Seachem Flourish is a comprehensive supplement containing both micro and macro elements. Flourish Trace is strictly a micro-nutrient supplement intended for more frequent use to replace elements that are depleted daily.
How often should I dose Seachem Flourish Trace?
The recommended dose is 5 mL (1 capful) for every 80 L (20 US gallons) twice a week. In heavily planted tanks, it can be used daily to ensure constant mineral availability.
Will this cause algae?
No. Because it lacks the phosphates and nitrates that primarily fuel algae blooms, Flourish Trace helps plants outcompete algae by ensuring they aren't "limited" by a lack of trace minerals.
Seachem Flourish: The primary comprehensive fertilizer to use as your weekly baseline alongside Flourish Trace.
Seachem Flourish Excel: Provides the bio-available organic carbon needed to fuel the growth stimulated by trace mineral replenishment.
Seachem Flourish Tabs: Use these to provide a long-term "slow release" of minerals directly to the roots of heavy-feeding plants like Swords and Crypts.
