In natural ocean water, this alkali metal is present in an average concentration of 408 mg\/l. In a saltwater aquarium, the potassium concentration is usually kept stable by regularly changing the water. Nevertheless, a lack of potassium can occur in individual aquariums tanks due to the use of zeolites and other adsorbents. One sign of a possible lack of potassium is clear discolouration of corals and retraction of polyps. The potassium level in a saltwater aquarium should be checked regularly to ensure that the level is between 380 and 420 mg\/l.\u003c\/p\u003e\u003cp\u003eThe Tropic Marin Potassium+ Pro Test Kit allows the Aquarist to determine the potassium concentrations reliably with a resolution of 5 mg\/l.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"Tropic Marin","offers":[{"title":"Default Title","offer_id":57054756536651,"sku":"TROPIC-POTPROTEST","price":32.77,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/7065\/4027\/files\/28390_testkit_professional_k.jpg?v=1776425708","url":"https:\/\/krakencorals.co.uk\/products\/tropic-marin-potassium-pro-test-kit","provider":"Kraken Corals","version":"1.0","type":"link"}
