Dosing one without the other for extended periods can pull the two parameters out of the ratio corals need.\u003c\/p\u003e\n\u003ch4\u003eWhy does alkalinity need to be dosed carefully?\u003c\/h4\u003e\n\u003cp\u003eRaising it too far or too fast can stress corals and, in tanks running high calcium, cause calcium carbonate to precipitate out of solution. Seachem recommends not raising alkalinity by more than 1 meq\/L in a 24 hour period, and testing before increasing the dose.\u003c\/p\u003e\n\u003ch4\u003eWill it cloud the water?\u003c\/h4\u003e\n\u003cp\u003eDosed at the recommended rate into a high-flow area, Reef Fusion 2 disperses without clouding. Adding it directly on top of Reef Fusion 1 concentrate, or dosing well above the stated rate, can cause temporary cloudiness or precipitation.\u003c\/p\u003e\n\u003ch4\u003eIs it reef-safe for clams and inverts?\u003c\/h4\u003e\n\u003cp\u003eYes. Reef Fusion 2 is formulated for reef aquariums housing corals, clams and other calcifying invertebrates, the animals that draw carbonate hardness down as they build skeleton and shell.\u003c\/p\u003e\n\u003ch4\u003eHow long will a 500 mL bottle last?\u003c\/h4\u003e\n\u003cp\u003eFor a 200 L system dosed at the standard rate (8 mL per dose, every 1-2 days), a 500 mL bottle will last roughly 2-4 months. Larger tanks or more frequent dosing will use it faster; test regularly and adjust accordingly.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":55242264543523,"sku":"AA0854","price":29.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/1219-reef_fusion_2-4_l-scaled.png?v=1782710547","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/seachem-reef-fusion-2-500ml","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
