GLA Micros II - Micromix: DTPA & EDTA Chelated Micronutrient Blend (Copper-Free) - 0.5lb Bag

GLA Micros Micromix II – Shrimp-Safe Trace Mix (Copper-Free) for Nature Aquariums (Bag)

Chelated Micronutrient Blend Without Copper for PPS-Pro & EI Fertilizer Dosing

GLA Micros Micromix II is a professional-grade, copper-free dry micronutrient blend formulated specifically for planted aquariums with sensitive livestock, including ornamental shrimp and invertebrates. It delivers a complete spectrum of essential trace elements—including iron (Fe-DTPA), manganese, zinc, boron, and molybdenum—chelated with DTPA and EDTA for stability and consistent availability across a wide range of aquarium water parameters.

GLA Micromix II is custom formulated and blended in our facility specifically and exclusively for planted aquariums and modern aquascaping systems. Unlike general-purpose agricultural or crop trace blends that have been adapted for aquarium use (such as Plantex CSM / NutriTrace), Micromix II is designed for submerged aquatic plant uptake and long-term stability in closed aquarium environments, where nutrient behavior, dilution, water clarity, and livestock sensitivity must be carefully managed.

Balanced Trace Levels for Consistent Dosing

In aquariums, trace elements accumulate differently than in soil-based systems. GLA Micromix II uses controlled micronutrient concentrations that support healthy plant growth across a wide range of aquascape styles without excessive trace input. This allows aquarists to dose predictably and fine-tune fertilization based on light intensity, CO2 injection, and plant mass while minimizing unnecessary trace buildup over time.

Clean, Pure, and Designed for Shrimp-Safe Systems

GLA Micromix II contains no fillers, bulking agents, or unnecessary additives. It is cleanly blended to dissolve predictably and avoid the dusty or “dirty” appearance often associated with commodity trace mixes. The copper-free formulation supports clear water and stable conditions in shrimp-focused and sensitive planted aquariums.

Advanced Chelation for Aquarium Conditions (DTPA + EDTA)

Using a combined DTPA + EDTA chelation strategy, Micromix II provides stable, bioavailable iron and trace elements across a wide range of pH and hardness levels. This makes it fully compatible with PPS-Pro and Estimative Index (EI) dosing systems while maintaining predictable nutrient availability in copper-free environments.

Copper-Free by Design

Micromix II contains no copper. This makes it especially well-suited for shrimp-focused planted aquariums, copper-sensitive livestock systems, or aquascapers who prefer to eliminate copper entirely while maintaining a complete and balanced micronutrient profile.
