Korallen-Zucht Coral Vitalizer – 10 ml

The new Coralfood Concentrate contains both liquid and solid elements, providing liquid to SPS corals as well as several soft corals. Does not increase PO4 or NO3.

First results can be seen after 7 to 10 days. When the corals are used to the feeding you will notice increased polyp expansion, e.g. of Acropora are fully extended even during the light period.

Corals retain their bright, natural color. Increases coral growth.

We recommend a dosing of 1-3 drops per 100L/25 gallons /day, depending on the live stock in the tank.

Compatibility

What it is. Coral food. KZ’s catalogue: a special food source for all kinds of corals, especially SPS and soft corals and the difficult Goniopora and Alveopora; it does not raise phosphate or nitrate; it produces natural, bright colouration and healthy growth, and extreme polyp expansion even in daylight and even on Acropora. Moderate overdosing is consumed by the tank’s own biology.

Where this sits in the Korallen-Zucht range. KZ build everything around four basis products (ZEOvit zeolite media, ZEObak, ZEOfood and ZEOstart), which together are the ZEOvit system. Everything else in the range, this product included, is a layer on top: colour products, problem solvers, and single elements. KZ’s own guidance is that the products can each be used separately, without the complete ZEOvit system and without the other KZ products, but that the full effect in quality and colouration comes only from running the system.

No ozone and no UV while you are running the ZEOvit system. That is KZ’s instruction, and the reason is the point of the system: ozone and UV destroy the microorganisms and elements the whole method depends on.

KZ’s own target water parameters, for any tank running their products: calcium 400 to 410 mg/L, magnesium 1,260 to 1,280 mg/L, carbonate hardness 6.5 to 8, potassium 380 to 400 mg/L, salinity 33 to 35 ppt. They add a warning worth repeating: higher figures bring no advantage. Neither growth nor colouration in SPS corals is improved by pushing past these, and higher levels tend to have negative effects.

Dosage & Directions

Korallen-Zucht’s own dose. 1 drop per 100 litres, three times a week. Bulk Reef Supply’s figure is 1 to 3 drops per 25 US gallons daily, dosed during the dark period if you can, adjusted to how heavily the tank is stocked.

Two dosing figures circulate for this product. The retail label and Bulk Reef Supply both give 1 to 3 drops per 100 litres or 25 US gallons daily. Korallen-Zucht’s own 2018 Easy Reefing guide gives 1 drop per 100 litres three times a week. Where the two disagree we print Korallen-Zucht’s own, and if you are new to the product the lower rate is the one to start on: you can always dose more.

How and where it goes in. Directly into the tank, into the flow. All equipment stays running.

Start below the figure, not at it. KZ’s own instruction for a first-time user, a lightly stocked tank, or a tank with little growth: reduce the dosage recommendation and adjust upward. Their words: do not act on the principle that the more the merrier.

Calculate on gross volume. KZ ask you to use the gross water amount for dosing arithmetic, not a net figure with rock and sand deducted.

Refrigerate it after opening. Bulk Reef Supply state a 12-month shelf life once opened, refrigerated. It is a food, and it behaves like one.

Pack Size

This listing is the 10 ml pack.

We stock it in 10 ml, 50 ml and 100 ml. The contents are identical; only the bottle changes. If you are dosing a large system daily, the larger packs are the ones to ask about.

Buy the size you will actually get through. These are concentrated additives dosed in millilitres and drops. A 5-litre container on a nano tank is not a saving; it is a bottle that will outlive its usefulness on the shelf.

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.
