What does kalkwasser do in a reef tank?
Kalkwasser is the German word for calcium hydroxide, a relatively inexpensive reef tank additive that will help you keep your calcium and pH levels nice and high in your tank. For some reason, the term kalkwasser has become part of the mainstream vernacular in the saltwater aquarium hobby.
What is kalkwasser made of?
Kalkwasser is water mixed with powdered lime or calcium hydroxide. The kalkwasser additives aquarists purchase are made of dried powder or kalk, and this powder is mixed with purified RO/DI water. Two Little Fishes Kalkwasser and Brightwell’s Kalk +2 are recommended kalkwassers.
Does kalkwasser dissolve?
Once it’s fully mixed its often referred to as a fully saturated solution meaning there is as many calcium and hydroxide ions dissolved in the water as their can be. After that, mixing it wont make any additional kalkwasser dissolve into the solution, in fact the opposite will happen.
How long does it take for kalkwasser to settle?
Grower of the Small Polyps With 3 sealed buckets this allows about 5-6 days to let everything settle before use.
Can I use a dosing pump for kalkwasser?
yes, people use dosing pumps to add kalk. It works better than dosing kalk via auto top off. “Adding 1.25% of the tank volume with saturated limewater will boost the pH instantly by about 0.7 pH units, but the effect rapidly wanes as the system pulls in more CO2 from the air.”
Does Kalkwasser raise salinity?
The kalkwasser when dissolved in salt water will also result in a high localized calcium concentrations. This will lead to the precipitation of calcium carbonate. So, you would actually be loosing more calcium carbonate to precipitation than you’d be gaining. Kalk will not affect salinity as others have stated.
How long does Kalkwasser last?
The limewater should last a long time, easily a month. Premixing that way is fine. I mix a 5g container at a time, and drip from it for a few weeks. More shaking is not recommended, as that will degrade the mix.
How long should kalkwasser sit?
Let the kalkwasser solution sit for 30 minutes before using. Activate your ATO and monitor the pH of your aquarium as the kalkwasser solution is being dosed, not exceeding increases of 0.20 pH.
How much Kalkwasser do you use?
