Tropic Marin Coral K+ Elements 1000 ml – Essential Cationic Trace Elements

Tropic Marin Coral K+ Elements (formerly known as Pro-Coral K+ Elements) is a high-purity liquid supplement designed to supply marine reef aquariums with essential cationic trace elements. These minerals are vital for the biological processes within coral cells and are heavily consumed during the development of aragonite skeletons. By replenishing elements like Strontium, Iron, and Manganese, this supplement ensures that corals maintain their natural, vibrant coloration and achieve maximum growth rates without the risk of deficiency-led bleaching.

Targeted Growth and Coloration Booster

Coral K+ Elements focuses on the positively charged (cationic) ions that are most frequently depleted in closed reef systems.

Comprehensive Cationic Profile: Supplies a precise blend of Strontium, Barium, Iron, Manganese, Copper, Zinc, Nickel, Chrome, Cobalt, and Boron in pure mineral form.
Intensifies Natural Pigmentation: Specifically formulated to prevent color loss in stony corals (SPS/LPS) by providing the metal-based catalysts required for pigment production.
Promotes Skeletal Hardness: Delivers the secondary minerals needed to strengthen the calcium carbonate matrix of reef-building invertebrates.
Easy and Flexible Dosing: The concentrated liquid formula is ready for immediate use, making it ideal for both manual daily additions and automated dosing pumps.
Ionic Balance Support: When used in conjunction with Tropic Marin A- Elements, it provides a complete seawater trace element profile without disrupting the aquarium's delicate ionic equilibrium.

FAQ Section: Common Questions

Do I really need both K+ and A- Elements?

Yes. Trace elements are divided into cationic (K+) and anionic (A-) groups. To provide a complete natural seawater profile, both solutions should be used together. K+ provides metals like iron and strontium, while A- provides elements like iodine and molybdenum.
Can I mix K+ and A- Elements in the same dosing bottle?

No. These solutions should be kept separate and dosed individually to prevent the elements from reacting or precipitating before they enter the aquarium.
How often should I test my trace elements?

While daily dosing keeps levels stable, we recommend an ICP-OES water test every 2–3 months to verify that no specific elements are being over-accumulated or under-supplied.
Is this safe for shrimp and other invertebrates?

Absolutely. When used at the recommended dosage, these mineral elements are essential for the metabolic health and molting processes of crustaceans and mollusks.
