These usually have a \"stem\" which can be easily removed with pliers if it bothers you. Now you can more easily glue the coral into your reef structure. First, turn off the flow pumps. Then put a small glue ball on the underside of the cutting stone and carefully submerge the coral upside down (with the glue ball facing upwards) under water. The cyanoacrylate polymerizes when it comes into contact with water and now forms a thin outer layer, while the inside is still liquid. Now find the desired position in the reef and place the coral cutting there by briefly rubbing the cutting stone against the rock. The glue ball bursts and the liquid glue can now bond to the cutting stone and reef rock. Hold the coral pressed against the rock for a few seconds without moving until the glue has completely hardened. After another 5 minutes you can turn the flow pumps back on.\u003c\/p\u003e","brand":"Coralaxy","offers":[{"title":"20 g","offer_id":55725662699894,"sku":"52-001-01","price":12.9,"currency_code":"EUR","in_stock":true},{"title":"50 g","offer_id":55725662732662,"sku":"52-001-02","price":24.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/5345\/9454\/products\/2381.jpg?v=1710239684"},{"product_id":"tropic-marin-o-megavital-micro","title":"Tropic Marin O-Megavital Micro","description":"\u003cp\u003e In addition to polyunsaturated fatty acids and vitamins, the energy-rich complete feed contains a seaweed additive.

The unit of density is g\/cm \u003csup\u003e3\u003c\/sup\u003e or, more simply, g\/l. A density measurement measures how much a single liter of a liquid weighs. One liter of pure water weighs approximately 1000 g, so its density is 1.000 g\/l. In addition to the water particles, sea water also contains various salts, which is why it is somewhat heavier than pure water. So its density is approximately 1.025 g\/l.\u003c\/p\u003e\n\n \u003cp\u003eSince liquids expand or contract depending on the temperature and thus change their volume, the temperature has a decisive influence on the salinity or density.
