Thicker or crystallising additives, like some calcium or alkalinity supplements, wear the tube faster.\u003c\/p\u003e\n\u003ch4\u003eDo I need to recalibrate after fitting a new tube?\u003c\/h4\u003e\n\u003cp\u003eYes — check delivered volume with the ReefDose Measuring Cylinder before trusting the schedule again.\u003c\/p\u003e\n\u003ch4\u003eMy channel is under-dosing — is this the fix?\u003c\/h4\u003e\n\u003cp\u003eUsually, yes. A worn head tube is the most common cause of gradual under-dosing. If the head won't turn at all, replace the gear motor instead.\u003c\/p\u003e","brand":"RedSea","offers":[{"title":"Default Title","offer_id":54774161834275,"sku":"RED838","price":24.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/red-sea-reefdose-head-tube-h-43876698259747.webp?v=1790239292","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/red-sea-reefdose-head-tube-hose-barbs","provider":"Nicks AOT","version":"1.0","type":"link"}
