Paired with carbon in Clear-Carb, it keeps water clear and starves nuisance algae of the phosphate it needs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is this different from Zeo-Carb?\u003c\/strong\u003e\u003cbr\u003eClear-Carb is carbon plus ClearMax, which targets phosphate. Zeo-Carb is carbon plus zeolite, which targets ammonia and is freshwater only. Pick Clear-Carb for phosphate and all-around water polishing in fresh or salt water.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow often do I replace it?\u003c\/strong\u003e\u003cbr\u003eEvery 3 to 4 weeks. Once the carbon and ClearMax are saturated they stop working, so this insert is replaced rather than rinsed and reused.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it reef safe?\u003c\/strong\u003e\u003cbr\u003eYes. Both the carbon and ClearMax are safe for marine and reef aquariums, and phosphate control is a common goal in reef keeping.\u003c\/p\u003e","brand":"Fluval","offers":[{"title":"Single","offer_id":48927188058331,"sku":"19626","price":5.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/5209\/3403\/files\/image_b3aef6a1-acb9-485e-b6d3-f474a159f8a2.jpg?v=1782920490","url":"https:\/\/squeakysaquatics.com\/products\/fluval-ac20-30-clear-carb-insert","provider":"Squeaky's Aquatics","version":"1.0","type":"link"}
