Red Sea Coral Colors C 500 ml

Red Sea Coral Colors C / Iron Supplement supplies a complex of eight light metals as part of the complete complementary element range corals need.

IRON Supplement is part of the complete range of complementary major, minor and trace element complexes which together provide the needs for coral growth.

A complex of eight light metals that includes iron, manganese, cobalt, copper, aluminum, zinc, chrome and nickel.

These micro-elements are essential for many bio-chemical metabolic processes, including respiration, production of energy, chlorophyll and photosynthetic catalysts. C elements are related to the green/yellow chromo-proteins.

Compatibility

Marine and reef aquariums only. None of the Reef Care Program supplements belong in a freshwater tank.

Coral Colors C — Red Sea now call this line Trace Colors, so this is Trace Colors C under its earlier name.

It supplies iron plus seven complementary light metals: manganese, cobalt, copper, aluminium, zinc, chrome and nickel. These drive respiration, energy production, chlorophyll synthesis and photosynthesis, and they are the elements associated with the green pigments.

Red Sea build the four Trace Colors supplements as a set covering the 31 minor and trace elements found in coral skeleton and tissue — all 31 are needed by every stony coral, whatever colour it happens to be. Red Sea recommend running them alongside NO3:PO4-X for nutrient control.

Dosage & Directions

1 ml raises iron in 100 litres (25 US gal) by 0.01 ppm.

Red Sea tie the Trace Colors dose to calcium consumption rather than to tank volume, on a 10:1 rule: 1 ml of each colour supplement for every 20 ppm of calcium you have added per 100 litres. A tank growing coral fast consumes calcium fast and needs the trace elements at the same pace; a tank that is barely growing needs almost none.

That is why there is no fixed daily dose. Dosing these to a schedule instead of to consumption is how people end up with elevated trace elements and no idea why the colour has gone off.

Red Sea's whole programme is built on dosing to a measured requirement rather than to a schedule. Test first, work out what the tank is actually consuming, and dose that. Red Sea publish a MyRecipe calculator that does the arithmetic from your test results and tank volume.

This is the bottle to be most careful with. It contains copper and several other metals that are toxic to invertebrates well above trace level, which is exactly why the dose is tied to consumption rather than left to judgement.

Pack Size

Red Sea make each Trace Colors supplement in 100 ml, which is the size in the four-bottle value pack, and in 500 ml as a single bottle.

Because the dose follows calcium consumption, a 500 ml bottle lasts a long time on a soft-coral tank and no time at all on a heavily stocked SPS system. Buy to your calcium demand, not to your tank volume.

Keep it closed, cool and out of direct light, and out of reach of children.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months' remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.
