Description

PURE: Reef Kalkwasser is a pure calcium hydroxide with unmatched purity and solubility characteristics.

MAINTAIN: Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that will maintain calcium concentrations at natural sea water levels. Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly.

CAPACITY: Reef Kalkwasser’s capacity to perform these functions is dependent on evaporation rate and CO2 concentration.

USE: If evaporation rate and CO2 concentration are insufficient you can provide additional calcium with Seachem’s Reef Advantage Calcium, Reef Complete, or Reef Calcium, and carbonate alkalinity with Reef Builder or Reef Carbonate.

DIRECTIONS: Never add this product directly to the tank. Add 3g (1 teaspoon) to 4L (1 US gallon) of water and mix to dissolve. If using pure water, a fully saturated solution is prepared by adding 6g (2 teaspoons) to 4L (1 US gallon). Drip solution into tank. Beware of overdose and use only what is needed to maintain desired calcium level.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $7 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Seachem products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
