Not suitable for use without testing calcium and alkalinity first, since dosing blind can push levels outside the safe range. Not intended to be dosed on its own long-term - it is designed to be paired with Reef Fusion 2 so calcium and alkalinity rise together rather than drifting apart.\u003c\/p\u003e\n\n\u003ch3\u003eDosage and directions\u003c\/h3\u003e\n\u003cp\u003eShake well before use. Dose 1 mL of Reef Fusion 1 per 25 L (6.5 US gallons) of aquarium water every 1-2 days, added to a high-flow area of the tank. Wait several minutes, then dose Reef Fusion 2 separately at the same rate into a different part of the tank. Do not exceed 4 mL per 25 L of either product in a single day. Each standard dose contributes roughly 4 mg\/L of calcium; use test kit results to adjust frequency and volume so calcium stays around 410-430 mg\/L and alkalinity stays around 4-6 meq\/L.\u003c\/p\u003e\n\n\u003ch3\u003eCost per litre\u003c\/h3\u003e\n\u003cp\u003eAt the confirmed dosing rate of 1 mL per 25 L, a 500 mL bottle delivers 500 doses, each treating 25 L of system water - around 12,500 litres of dosed water across the life of the bottle. At $29.95 per 500 mL, that works out to under 1c per litre of tank water dosed.\u003c\/p\u003e\n\n\u003ch3\u003eCare and safety notes\u003c\/h3\u003e\n\u003cp\u003eNever mix Reef Fusion 1 and Reef Fusion 2 concentrates together before adding them to the tank - dose them separately, a few minutes apart, into different areas of the aquarium to avoid the two reacting and precipitating in the bottle or in the water. Test calcium and alkalinity regularly and adjust the dose gradually rather than jumping straight to the maximum rate.\u003c\/p\u003e\n\n\u003ch3\u003eGoes well with\u003c\/h3\u003e\n\u003cp\u003eReef Fusion 1 is designed to be dosed 1:1 with \u003cstrong\u003eReef Fusion 2\u003c\/strong\u003e, its alkalinity and carbonate counterpart, so the two elements are replenished together rather than drifting out of balance.\u003c\/p\u003e\n\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eCovered by the standard consumer guarantees under Australian Consumer Law.

Using Reef Fusion 1 alone for an extended period can let alkalinity fall behind calcium demand.\u003c\/p\u003e\n\n\u003ch4\u003eHow often should I test before adjusting the dose?\u003c\/h4\u003e\n\u003cp\u003eTest calcium and alkalinity at least weekly when starting a dosing routine, and more often in a heavily stocked or fast-growing reef tank, then adjust the dose gradually based on those results rather than the maximum rate on the label.\u003c\/p\u003e\n\n\u003ch4\u003eWill it cloud the water?\u003c\/h4\u003e\n\u003cp\u003eDosed correctly and separately from Reef Fusion 2 into a high-flow area, Reef Fusion 1 should not cloud the water. Cloudiness generally happens if the two parts are mixed directly together or if the dose is increased too quickly.\u003c\/p\u003e\n\n\u003ch4\u003eIs it reef-safe for clams and inverts?\u003c\/h4\u003e\n\u003cp\u003eYes, it is formulated for reef aquariums containing corals, clams and other calcifying invertebrates, and is one of the main ways to supply the calcium those animals need to grow their shells and skeletons.\u003c\/p\u003e\n\n\u003ch4\u003eHow long will a 500 mL bottle last?\u003c\/h4\u003e\n\u003cp\u003eThat depends on tank size and dosing frequency. At the standard rate of 1 mL per 25 L every 1-2 days, a 500 mL bottle provides roughly 500 doses, so a smaller reef tank dosed every second day will get considerably more use out of one bottle than a large, heavily stocked system dosed daily.\u003c\/p\u003e","brand":"Seachem","offers":[{"title":"Default Title","offer_id":55242264510755,"sku":"AA0853","price":29.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/1209-reef_fusion_1-4_l-scaled.png?v=1782710546","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/seachem-reef-fusion-1-500ml","provider":"Nicks Aquarium Oceanarium Terrarium","version":"1.0","type":"link"}
