Seachem Laboratories Reef Fusion 2 Supplement 17 fl oz

Caring for a reef tank means watching the small numbers so your corals never have to. Seachem Laboratories Reef Fusion 2 is the alkalinity component of a two-part system, offered here in a compact 17 fl oz size. Together with Reef Fusion 1, it is made to help you keep calcium and alkalinity in the steady balance a reef aquarium needs, one measured dose at a time.

• Provides alkalinity to your reef aquarium, working alongside the calcium that Reef Fusion 1 supplies.
• Made with a mixture of carbonates and bicarbonates at an alkalinity of 4400 meq/L.
• Designed to restore and maintain alkalinity, so you can bring a low reading back up and hold it there.
• Gives calcareous species the essential carbonate Seachem says they need for growth.
• The 17 fl oz size is a sensible starting point or a fit for smaller tanks that use supplement slowly.
• Part of the Reef Fusion system, formulated to provide the essentials for the reef aquarium.
• Pairs directly with Reef Fusion 1 to maintain both calcium and alkalinity levels in tandem.
• A liquid supplement that slots neatly into your regular dosing schedule, by hand or by doser.
• Backed by Seachem Laboratories, a familiar name in aquarium care.
• For best results, dose as directed and let your test kit guide the amount.

In an active reef, alkalinity gets consumed right along with calcium, and replacing it on a regular cadence is part of keeping conditions consistent for your corals. Topping up calcium on its own tends to let alkalinity drift downward, which is the very swing this component is built to settle. Reef Fusion 1 and Reef Fusion 2 are the foundation of a system formulated to provide the essentials for the reef aquarium, and Seachem notes that when the two are used together as directed, they help maintain the calcium and alkalinity your tank depends on. Keep this 17 fl oz bottle of Reef Fusion 2 next to its calcium partner, test often, and dose to your readings so your reef stays on an even keel.
