Compatibility

What it is. A bacterial product aimed at cyanobacteria. KZ's catalogue: a special bacterial strain to eliminate cyanobacteria. The dosing guide is more specific about the mechanism — bacteria that outcompete the cyanobacteria, and, in KZ's own words, no poison. Bulk Reef Supply confirm it contains no antibiotics and does not affect biological filtration.

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.

KZ have you use it in combination with Coral Snow, which enhances the effect. Bulk Reef Supply add ZEOzym to that pairing.

Dose it on a different day from the iodide concentrates — that is KZ's instruction on those products, which name CyanoClean, ZEObak and Bio-Mate.

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.

Pack Size

This listing is the 10 ml pack.

We stock it in 10 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.
