CONTINUUM Reef Basis Kalkwasser

Description

High quality calcium hydroxide
Provides essential calcium for increased growth rates in corals and marine organisms
Contains no acetate, EDTA, gluconates, polygluconates or other unnecessary organics to pollute your aquarium.

Reef Basis Kalkwasser is a high quality calcium hydroxide, the original German limewater method of adding calcium, providing essential calcium for increased growth rates in corals, coraline algae, crustaceans and many other marine organisms. It contains no acetate, EDTA, gluconates, polygluconates or other unnecessary organics to pollute your aquarium.

Use in aquarium keeping.
Kalkwasser is primarily designed for maintenance and does not work rapidly, so you should first use our ReefBasis Calcium if you have severely depleted calcium levels and need to raise them rapidly. Proper control of calcium level is imperative for the health and growth of corals and many other invertebrates. Continuum recommends that you maintain a calcium level of between 410 and 450 mg/L (ppm), an alkalinity level of 7 to 11 dKH (2.5 to 4 meq/L), and a magnesium level of 1250 to 1350 mg/L (ppm). Note: Aquarists keeping SPS corals should consider keeping alkalinity at 7 to no more than 9 dKH (2.5 to 3.21 meq/L).

Expert use.
This product is only meant for use by advanced hobbyists that are familiar with Kalkwasser. Never add powder directly to the aquarium! Dissolve 6 grams, about 2 teaspoons of product in 1 gallon of purified water to make a saturated solution. Stir vigorously, let stand for several hours. A white precipitate will form on the bottom of the container, and a crust may form on the top of the solution, this is normal. Decant the clear liquid into a dosing system and drip slowly over several days. Discard precipitate. Each gallon of Kalkwasser solution will raise the calcium level about 48 ppm in a 20 gallon (80 L) aquarium. Test the calcium level with a good quality test kit and adjust the addition rate as necessary to maintain the desired level.

Caution: Keep out of reach of children. Not for human consumption.
Contains strongly alkaline calcium hydroxide, if ingested drink plenty of water or acidic fruit juice, consult your medical practitioner or a poison control center.
If in eyes flush with water for 15 minutes, consult your medical practitioner. If on skin flush with water.

Continuum Reef Basis Kalkwasser for SG reef calcium and alkalinity

Kalkwasser, or limewater, is the classic German method of supplying calcium and alkalinity together, and it remains a favourite among Singapore reefers running calcium-hungry systems. Reef Basis Kalkwasser is a high-quality calcium hydroxide with no acetate, EDTA, gluconates or other unnecessary organics to pollute the tank. Dosed properly, it provides essential calcium for stronger growth in corals and other marine organisms while helping support pH, which is handy when a closed flat keeps tank CO2 elevated.

Because kalkwasser is strongly alkaline, we stress careful, slow dosing, ideally via top-off or a stirrer rather than dumping it in. It pairs well with an auto top-off, replacing water lost to evaporation while delivering calcium and alkalinity in one stream. Test and dose toward targets, and never overdose, as a sudden swing can crash a reef quickly in our warm conditions.
