Sustain color and metabolic performance with true trace-level iron. Isol8:Fe is an ultra-pure, stabilized iron supplement engineered for ICP-guided trace management within the Captiv8 BluePrint methodology. At controlled levels, iron supports zooxanthellae function, enhances greens/yellows in photosynthetic corals, and fuels healthy macroalgae/refugium growth—without disturbing nutrients or water clarity.
ICP-driven micro-dosing to correct verified Fe deficits precisely.
High-purity, reef-safe formula for sensitive, low-nutrient systems.
Predictable concentration for manual or automated micro-additions.
BluePrint-ready—integrates cleanly with Captiv8 schedules and other Isol8/Aragonite supplements.
Doser-friendly for consistent, small additions after calibration.
Test first: Obtain a recent ICP analysis and confirm iron levels vs. your target.
Calculate dose: Use the label’s dose-to-µg·L⁻¹ relationship against total system volume.
Split corrections: For larger adjustments, add multiple micro-doses over several days rather than one addition.
Add in high flow (sump/overflow). Avoid direct contact with coral tissue.
Verify & maintain: Re-test on your normal ICP cadence; convert to a modest maintenance dose as needed.
Do not exceed label guidance—iron is highly reactive at trace levels.
Tip: Dose away from fresh GFO/resins and other strong adsorbers for consistent contact time.
Keep core parameters stable: Alk 7.5–9 dKH, Ca 420–450 ppm, Mg 1280–1380 ppm, Salinity 1.025–1.026, Temp 77–79°F (25–26°C).
Log every trace addition; align with your BluePrint schedule and water-change cycle.
If running a refugium, begin with very small doses and watch macroalgae color and growth rate.
Avoid simultaneous additions with strong oxidizers; separate iron dosing from phosphate control measures to minimize precipitation.
Safe for reef systems when used strictly at trace levels per testing and label guidance.
Works alongside skimmers, carbon, phosphate media (dose at different times), bacterial programs, refugia, and amino/trace blends.
Not a medication and not intended for non-aquarium use.
