Keep rubidium (Rb) aligned with natural seawater for balanced reef chemistry. Isol8:Rb is an ultra-pure, stabilized rubidium supplement designed for ICP-guided trace management within the Captiv8 BluePrint methodology. Precise micro-dosing supports ionic equilibrium and healthy reef microbiology—without affecting nutrients or water clarity.
ICP-driven micro-dosing to correct verified Rb deficits accurately.
High-purity, reef-safe formulation for sensitive, low-nutrient systems.
Predictable response when added in small, controlled increments.
BluePrint-ready—integrates cleanly with other Isol8 traces and major-ion programs.
Doser-friendly concentration for automated micro-additions after calibration.
Test first: Review recent ICP results and confirm your Rb target.
Calculate dose: Use the label’s dose-to-µg·L⁻¹ (ppb) relationship for 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 is observed.
Do not exceed label guidance—precision matters with trace elements.
Tip: Time trace additions after water changes or fresh media swaps for consistent contact time 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, frequent doses are more stable than occasional large ones.
Space dosing several hours from strong oxidizers or metal-removal resins.
Dose at a consistent time daily if automated.
Safe for SPS/LPS/soft coral systems when used strictly at trace levels per testing and label guidance.
Works alongside skimmers, carbon, PO₄ media, refugia, bacterial programs, and major-ion dosing (dose at different times).
