Zoolek Aquatest K<\/b> is a complete kit for determining the concentration of ions <\/span>potassium (K)<\/b> in fresh water. It enables the measurement of <\/span>in the range of 3 to 125 mg\/l<\/b>, enabling accurate monitoring of one of the essential macronutrients responsible for the proper metabolism of aquarium plants.<\/span><\/p>\n

Why measure potassium?<\/b><\/p>\n

Potassium (K),<\/b> alongside <\/span>nitrogen (NO\u2083) <\/b> and <\/span>phosphorus (PO4),<\/b> is one of the most important macronutrients essential for proper plant growth<\/b>.<\/span><\/p>\n

Unlike nitrogen and phosphorus, which are often present in sufficient or even excessive quantities in fish tanks, <\/span>potassium <\/b>is very rarely supplied in sufficient quantities naturally.<\/span><\/p>\n

Failure to monitor potassium levels leads to<\/b>a gradual deficiency, which manifests itself as<\/span>yellowing of older leaves<\/b>, the appearance of characteristic<\/span>holes in the leaf blades<\/b> and a general <\/span>weakening of plant growth<\/b>.<\/span> <\/b><\/p>\n

A potassium deficiency <\/b>also disrupts the transport of other nutrients within plant tissues, impairing their condition even when levels of <\/span>NO\u2083 and PO\u2084 are normal.<\/b><\/p>\n

On the other hand, <\/span>excessive potassium supplementation is not without consequences either<\/b>. Although high concentrations <\/span>K<\/b> is not toxic to fish and shrimps, but may lead <\/span>to impaired absorption of other elements, such as calcium, magnesium or trace elements, causing secondary deficiencies.<\/b><\/p>\n

Responsible aquarium keeping<\/b><\/p>\n

For most aquarium plants, the optimum potassium level is <\/span>between 10 and 20 mg\/l<\/b>, although its consumption depends primarily on the number of plants in the tank and their growth rate.<\/span>
\n<\/span>Regular testing of K levels<\/b> allows you to fine-tune fertiliser application rates, maintain a stable balance of macronutrients and provide plants with conditions conducive to healthy, even growth without the risk of deficiencies or excesses of nutrients.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
