The carbon dioxide gas will seek a point of equilibrium between the indicator solution and the aquarium water. As equilibrium is achieved, the colour of the indicator solution inside of the drop checker will change based on the concentration of CO2 in the aquarium water.\u003c\/p\u003e\u003cp\u003eIf the indicator solution is green in colour, then appropriate levels of carbon dioxide exist in the aquarium, and no action is required. If the solution in the drop checker changes to blue or yellow, then the CO2 levels in the aquarium are too low or too high, respectively.\u003c\/p\u003e","brand":"CO2Art","offers":[{"title":"Default Title","offer_id":57074431394175,"sku":"734011","price":5.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/5420\/6079\/files\/co2art_drop_checker_solution_15ml.jpg?v=1772674531","url":"https:\/\/finestaquatics.co.uk\/products\/co2art-aquarium-co2-drop-checker-solution-15ml","provider":"Finest Aquatics","version":"1.0","type":"link"}
