Korallen-Zucht Pohl’s K-Balance Potassium Concentrate 250 ml

Potassium is one of the major elements in seawater and natural levels are very similar to that of calcium levels, 380-410mg/liter. While not consumed as quickly as calcium, it is important to maintain appropriate levels to achieve ideal coral coloration and growth. KZ tests have shown tanks with known potassium deficiencies to show significantly better growth and coloration within days of K-Balance use. K-Balance contains multiple potassium salts in high concentrations.

• Can be used to enhance growth in SPS corals.
• Enhances blue/purple coloration in Tridacna clams and SPS corals.
• Can aid in preventing old-tank syndrome.

Note: Low potassium levels have following characteristics:

• Montipora stop growing, colors are dull to grey.
• Poccilopora and Stylopora with low potassium level look like they have been out of the water in the air, polyps are inside and color is light without depth and saturation.
• Blue Acropora are also washed-out.
• Seriatopora can show complete tissue necrosis within a few days.
• Turbinaria Reniformis stops growing.

Dosing: 1 mL/25 gallons per day

Warning: Do not increase dosage given on the label. Product is highly concentrated. We recommend to check potassium level regularly like Ca or Mg.

K-Balance Strong is especially useful to increase the potassium level in big tanks.

Compatibility

What it is. Potassium. KZ’s catalogue: contains several potassium compounds, maintains coral health and biological function, and enhances growth and colouration of all corals, especially blue-coloured SPS and LPS. They also credit it with preventing “old tank syndrome”. In the dosing guide: growth, colour and polyp expansion of all corals, to replace consumed potassium and hold a good level.

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.

K-Balance Strong is the same job at higher strength, for raising a low potassium level and for large tank volumes.

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 ml per 100 litres per day, adjusted to your own potassium level and consumption.

How and where it goes in. Directly into the tank, into the flow.

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.

Do not exceed the dose on the label. KZ’s own warning: the product is highly concentrated, and they ask you to test potassium as regularly as you test calcium or magnesium.

Natural seawater sits at 380 to 410 mg/L potassium. Bulk Reef Supply list the symptoms of a deficiency: Montipora stop growing and go dull or grey; Pocillopora and Stylophora look as though they have been out of the water, polyps in, colour washed out; blue Acropora fade; Seriatopora can lose tissue completely within days; Turbinaria reniformis stops growing.
