Reef Kalkwasser 500 g Seachem – Calcium Hydroxide for Reef Aquarium

Reef Kalkwasser Seachem is a very high purity calcium hydroxide intended for the preparation of limewater solutions. It helps maintain calcium at levels close to those of natural seawater while contributing to pH stability in reef aquariums.

SEACHEM

Main Features

Type: very pure calcium hydroxide.

Use: preparation of kalkwasser solution.

Function: maintenance of calcium and stabilization of pH.

Impact: increases pH without direct effect on carbonate alkalinity.

Compatibility: reef aquarium.

Kalkwasser Principle

Calcium hydroxide is used to prepare a limewater solution (kalkwasser). This solution helps directly maintain calcium and indirectly alkalinity, depending on the evaporation rate and CO2 concentration of the system.

When evaporation or CO2 supply is insufficient, a supplement in calcium or alkalinity may be necessary using dedicated supplements, without ever mixing them directly with the kalkwasser solution.

Target Audience

Reef Kalkwasser is an economical and effective solution, but it requires some discipline in its use. Beginner aquarists or those with limited time may prefer less technical alternative methods to maintain ionic parameters.

Available Sizes

250 g, 500 g, 1 kg, 2 kg.

Usage Instructions

Never add Reef Kalkwasser directly into the aquarium.

Add 3 g (about 1 teaspoon) to 4 L of osmosis water, then mix to dissolve.

For a fully saturated solution with pure water, add 6 g (2 teaspoons) for 4 L of water.

Administer the solution by dripping into the aquarium.

Regularly monitor the pH and carbonate alkalinity and adjust the addition rate to maintain a stable pH between 8.3 and 8.4.

Adding 4 L of a saturated solution to 150 L of water increases the calcium by approximately 24 mg/L.

Use only the clear solution above the deposit and avoid introducing any undissolved material into the aquarium.

Keep the container tightly closed and limit contact with air to prevent the formation of calcium carbonate by reaction with CO2.

FAQ

Reuse of Sediments

The sediments deposited at the bottom of the container after preparation are generally not reusable. Over time, undissolved calcium hydroxide reacts with CO2 to form calcium carbonate, which precipitates and does not redissolve.
