Captiv8 Reef BluePrint Lugol’s Solution supplies a balanced, reef-safe blend of elemental iodine (I₂) and iodide (I⁻) to restore and maintain natural-seawater iodine levels. Iodine is an essential ultra-trace element that supports coral health, polyp extension, soft coral growth (e.g., Xenia, leathers), macroalgae vitality, and crustacean molting.
Balanced I₂ + I⁻ formula for broad biological availability
Ultra-pure, reef-safe—no phosphates, nitrates, or dyes
Clear, fast-mixing solution; doses cleanly with no clouding
ICP-friendly for precise, test-based supplementation
Fine control via dropper—ideal for SPS/LPS and mixed reefs
Always base iodine dosing on ICP testing or a trusted lab; adjust for your system’s actual uptake.
Start low: Dose 1 drop (~0.05 mL) per 25 gal (95 L) daily for 7–10 days.
Test & tune: Check iodine; adjust dose to maintain your target (often near natural seawater).
Maintenance: Prefer small, consistent micro-doses over large, infrequent additions.
Application: Add to a high-flow area or sump. Do not mix in the same dosing head with high-pH additives; separate by 5–10 minutes.
If iodine tests above target or livestock show stress: stop dosing and perform a partial water change.
Safe with Ca/Alk/Mg programs, amino acids, and other Captiv8 Isol8™ traces when used as directed.
Reef-safe for fish and invertebrates. Avoid overdosing—iodine is potent at ultra-trace levels.
Ultra-pure Lugol’s iodine/iodide solution in purified water.
