Korallen-Zucht ZEOspur 2 – 250 ml

ZEOspur 2 is Korallen-Zucht’s advanced ZEOvit formula, developed from real-world reefing experience to achieve extreme coral coloration.

ZEOspur 2 is a product of permanent development of the ZEOvit®- system. It results from our practical experience of keeping corals with extreme coloration.

It is highly concentrated it is important not to chance dosing recommendation on the label: 1 ml /100 L/25 gallons each 8-10 days.

The result can be seen 24 h after dosing and reaches the highest level after 48 h.

With this trace element solution it is possible to influence the amount of zooxanthellae in the coral tissue. The coral itself has more energy for growth because the reduced zooxanthellae density requires less energy.

• Controlled reduction of zooxanthellae density for Acropora, Anacropora or Montipora.
• The reduction of zooxanthellae in the outer layers brings out the colors from deeper layers.
• To maintain color of highly colored corals. – Recommended in any tank system.

Compatibility

What it is. KZ's catalogue: for maintaining extreme colouration and brilliance. It contains elements that control and reduce zooxanthellae density, mainly in Acropora, Anacropora and Montipora — reducing the density in the outer layers is what lets the coral's own colour show, and KZ say the coral then has more energy for health and growth.

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.

ZEOspur Macroelements is the companion product — KZ describe it as the optimal addition to ZEOspur 2.

For a tank not on the ZEOvit system, KZ point at Trace Element Complex instead. ZEOspur 2 is the balanced trace element product for ZEOvit tanks.

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 400–410 mg/L, magnesium 1,260–1,280 mg/L, carbonate hardness 6.5–8, potassium 380–400 mg/L, salinity 33–35 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. Start at 0.5 ml per 100 litres every 8 to 10 days. That can be increased by 0.1 ml per 100 litres a week, up to a maximum of 1 ml per 100 litres every 8 to 10 days.

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.

Healthy corals only, and do not overdose. Three of KZ's own instructions, verbatim in effect: use only in tanks with healthy corals; do not overdose; do not shorten the dosing interval. The effect peaks about two days after dosing, so judging it any sooner will make you dose again too early.

Bulk Reef Supply are more cautious still. They recommend every 14 to 21 days, dosing the full amount at once, starting at half the suggested dose and raising it 10% at a time; and they warn against using it on newly acclimated corals or in new systems, because overdosing induces bleaching. KZ's own interval is the 8 to 10 days above; if you are new to the product, the slower approach costs you nothing.
