Product overview
Red Sea Trace Colors A – Iodine+ supplies iodine, bromine, and fluorine for marine tanks. Skimming and carbon filtration strip these halogens from the water. When they run low, coral tissue growth can slow and pink and purple colour can fade.
The liquid is made for coral soft-tissue health and chromoproteins. It is balanced to dose alongside Red Sea’s Foundation calcium and KH additives.
Key features
-
Pink and purple support: Iodine, bromine, and fluorine formulated to support pink chromoproteins.
-
Stress: Helps the mucus layer cope with oxidative stress under strong lighting, which can reduce bleaching risk.
-
Invertebrates: Trace elements crustaceans and ornamental shrimp need for normal moulting.
-
Liquid ions: Bioavailable form for coral tissue uptake.
-
Low residue: Inorganic trace mix; not an organic food, so it does not add the same waste load as coral foods.
-
Foundation pairing: Ratio is set to work with Red Sea calcium and KH programs for more predictable dosing.
Water and system compatibility
-
Water: Marine and reef aquariums only. Not for freshwater or planted tanks.
-
Corals: SPS, LPS, soft corals, and non-photosynthetic (NPS) species.
-
Doser: Stable unrefrigerated and unstirred in a dosing container.
Dosing and instructions
Always follow dosage & directions on product packaging.
Calculate true water volume. Dose daily per 100 litres, or scale to match calcium consumption:
-
LPS / SPS frags and growing tanks: 1 ml (or 1 ml per 100 g of calcium added)
-
Mixed reef: 1 ml (or 1 ml per 100 g of calcium added)
-
SPS-dominant: 2 ml (or 2 ml per 100 g of calcium added)
-
Ultra-low nutrient (ULNS): 2 ml (or 2 ml per 100 g of calcium added)
Iodine is reactive. Test before increasing the daily dose. Do not raise amounts without a suitable iodine test kit.
Storage
-
Bottle: Cool, dry cupboard out of direct sunlight. Do not refrigerate.
-
Doser: Use airtight lines to limit evaporation and crystallisation at the tips.
