Keep selenium (Se) in the optimal trace window for balanced reef biochemistry. Isol8:Se is an ultra-pure, stabilized selenium supplement engineered for ICP-guided trace management within the Captiv8 BluePrint methodology. True trace-level dosing supports Se-dependent enzymatic processes in reef microbiota and helps maintain overall system stability—without affecting nutrients or water clarity.
ICP-driven micro-dosing to correct verified Se deficits precisely.
High-purity, reef-safe formulation for sensitive, low-nutrient systems.
Predictable response when added in small, controlled increments.
BluePrint-ready—fits seamlessly alongside other Isol8/Aragonite components.
Doser-friendly concentration for consistent automated micro-additions.
Test first: Review a recent ICP report and compare Se to your target range.
Calculate dose: Use the label’s dose-to-µg·L⁻¹ (ppb) relationship for your total system volume.
Split corrections: If a larger increase is required, divide into multiple micro-doses over several days.
Add in high flow (sump/overflow). Avoid direct contact with coral tissue.
Verify & maintain: Re-test on your normal ICP cadence; convert to a small maintenance dose if ongoing uptake persists.
Do not exceed label guidance—precision matters with trace elements.
Tip: Make trace additions after water changes or fresh media swaps so contact time is consistent before export.
Keep core parameters steady: 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; small, regular doses are more stable than occasional large ones.
Space dosing several hours from strong oxidizers or metal-removal resins.
If running fresh carbon/resins, dose after media changes for repeatable results.
Safe for reef systems when used strictly at trace levels per testing and label guidance.
Works alongside skimmers, carbon, phosphate media, refugia, bacterial programs, and major-ion dosing (dose at different times).
