Tropic Marin Block Iodine is a professional-grade, highly concentrated multi-element solution engineered to restore essential halogens and trace minerals in marine aquariums. Part of the innovative Tropic Marin Block System, this solution utilizes a precise, ratio-based approach that links a primary indicator element to related trace elements that are consumed at the same biological rate. This smart formulation ensures that even rare elements—which often fall below the detection threshold of standard hobby testing—are safely and accurately replenished without the risk of overdosing. Block Iodine specifically delivers a balanced mix of iodine, fluorine, bromine, and selenium to support skeletal structure, metabolic enzyme activation, and rich tissue coloration across all coral species.
Key benefits:
Precision Ratio-Based Replenishment: Links the primary indicator element (iodine) to secondary trace minerals, keeping your water chemistry naturally balanced without complex math.
Skeletal Growth & Light Adaptation: Supplies essential halogens (iodine, fluorine, and bromine) that strengthen organic and inorganic coral skeletons while directly helping corals acclimate to high-intensity lighting.
Antioxidant Tissue Protection: Contains selenium, which acts as a natural antioxidant to protect delicate coral tissue from oxygen radicals and improve overall recovery.
Versatile Application: Equipped with an integrated dropper cap for quick manual adjustments, and remains perfectly stable for automated dosing pump systems.
Specifications:
Volume: 1000ml (1 Liter)
Form: Liquid mineral concentrate
Element Concentration per Liter: Iodine (I): 875 mg/L | Fluorine (F): 1110 mg/L | Bromine (Br): 435 mg/L | Selenium (Se): 0.5 mg/L
Water type: Marine Reef and Saltwater Aquariums
Intended users: Advanced reef keepers, coral aquaculturists, and hobbyists managing mixed reef or SPS-dominated systems
Suggested use:
Dosing Regimen: Add 2 ml per 26 US gallons (100 Liters) of aquarium water daily. This increases the concentration of iodine by 17.5 µg/l (ppb), fluorine by 22.2 µg/l (ppb), bromine by 8.7 µg/l (ppb), and selenium by 0.01 µg/l (ppb).
Maximum Dosage: Do not exceed a maximum daily dosage of 4 ml per 26 US gallons (100 Liters).
Pro Tip: For maximum accuracy, pair this dosing regimen with periodic Tropic Marin ICP water tests to monitor long-term trends and identify exact deficits.
Storage and safety:
Store in a cool, dark location away from direct sunlight to maintain long-term chemical stability.
Warnings:
Do not mix directly with other element solutions inside a single dosing reservoir; always add separately to the aquarium water column.
Keep out of reach of children.
What’s included:
1 x Tropic Marin Block Iodine (1000ml bottle)
Why choose:
Dosing individual trace minerals can easily lead to guesswork, dangerous chemical imbalances, or levels falling below standard test kit detection lines. Tropic Marin Block Iodine provides a safe, scientifically balanced, ratio-based method to restore vital elements together. It keeps your corals growing rapidly, protected from stress, and showing their deepest possible colors.
