Zoolek Aquatest Ca-Mg<\/b> enables the accurate determination of calcium ion levels <\/span>(Ca\u00b2\u207a) <\/b>and magnesium <\/span> (Mg\u00b2\u207a)<\/b> in fresh water. The measurement is based on a titration method, which involves gradually adding the reagent drop by drop until a distinct colour change in the sample is observed. The result obtained allows the concentration to be determined <\/span>calcium and magnesium in mg\/l, as well as total hardness (GH) expressed in German degrees.<\/b><\/p>\n

Calcium and magnesium \u2013 essential elements in a planted aquarium<\/b>
\n<\/span>In planted aquariums, it is not only the total hardness that is important, but also the ratio of calcium to magnesium. <\/span><\/p>\n

A situation may arise in which <\/span>GH<\/b> falls within the normal range, yet the plants still show symptoms of <\/span>magnesium deficiency. <\/b> Magnesium<\/b> plays a fundamental role; it is at the centre of the chlorophyll molecule responsible for photosynthesis. <\/span> <\/p>\n

Its deficiency <\/b>leads to stunted growth, deformation of leaves and a deterioration in the condition of the entire vegetation.<\/span>
\n<\/span>A magnesium-to-calcium ratio of approximately 1:5<\/b> is considered optimal<\/span>, as it promotes proper nutrient uptake and stable plant growth.<\/b><\/p>\n

The effects of Ca and Mg on plants and animals<\/b>
\n<\/span>Calcium deficiency<\/b>stunts plant growth, causes abnormalities in tissue structure and results in poor colouration. <\/span> <\/p>\n

Conversely, an excess of it,<\/b>which is often found in tap water, is associated with high <\/span>total hardness<\/b> and may hinder the absorption of magnesium and trace elements.<\/span>
\n<\/span>Total ion content <\/span>of Ca and Mg, i.e. total hardness (GH),<\/b> It is also of significant importance to fish and prawns. Many species tolerate a certain <\/span>GH range,<\/b> however, when it comes to breeding, rearing fry or keeping more demanding species, knowing the exact total hardness value becomes crucial.<\/span><\/p>\n

Responsible aquarium keeping<\/b>
\n<\/span>Regular testing of calcium, magnesium and total hardness<\/b> enables you to manage the water composition effectively, adjust fertilisation and prepare water tailored to the needs of plants, fish and shrimps. <\/span> <\/p>\n","protected":false},"excerpt":{"rendered":"
