Parameter	Details
What is kalkwasser?	A concentrated calcium hydroxide solution used to raise calcium and alkalinity in reef aquariums.
Benefits	Boosts coral growth and health. Helps counteract pH drop. Enhances alkalinity and calcium levels.
Dosing Considerations	Dose small amounts frequently instead of large doses. Turn off protein skimmer before dosing. Target calcium around 420-450 ppm.
Dosing Amount	Depends on tank size, but typical is 5-10ml per 10 gallons daily or every other day.
Measuring Calcium	Use a calcium test kit. Measure just before lights come on for an accurate low point reading.
Calculation	(Target calcium – measured calcium) x tank gallons / 50 = ml of kalkwasser to dose
Safety Tips	Avoid skin contact. Wear gloves and goggles. Have proper ventilation.

FAQs

How much kalkwasser do I mix per gallon?
You can typically mix about 1-2 teaspoons (5-10 grams) of kalkwasser per gallon of freshwater.

How much kalkwasser do you use?

How many grams of kalk per gallon?
Approximately 5-10 grams per gallon.

How many grams of kalkwasser per liter?
Around 1.3-2.6 grams per liter.

When should I start dosing Kalk?
Start dosing kalkwasser when your tank’s alkalinity and calcium levels need supplementation. Regular testing will help determine the right time to start.

How much vinegar do I add to kalkwasser?
Typically, you would add enough vinegar to create a saturated solution with the kalkwasser, but the exact amount can vary. Start with a small amount and add more as needed until the solution becomes clear.

How do you dose Kalk by hand?
You can manually add kalkwasser solution to your tank using a dosing container and slowly pouring it in. Ensure you don’t pour any undissolved particles into the tank.

Does kalkwasser increase alkalinity?
Yes, kalkwasser can increase alkalinity in your aquarium.

Should kalkwasser be clear?
Ideally, yes, kalkwasser should be clear once it’s properly mixed and settled. Cloudy kalkwasser may contain undissolved particles.

How do you mix Kalk?
To mix kalkwasser, add the appropriate amount of powder to a container with water and stir until it’s dissolved. Allow it to settle, and then use the clear solution for dosing.

Can I use a dosing pump for kalkwasser?
Yes, dosing pumps can be used to automate kalkwasser dosing for better control and consistency.

Does kalkwasser raise magnesium?
Kalkwasser primarily supplements calcium and alkalinity, but it may also increase magnesium levels slightly due to impurities in the product.

How long does kalkwasser take to raise pH?
Kalkwasser can have an immediate effect on pH, but long-term pH stability depends on factors like tank size and the buffering capacity of your water.

How much salt for 1.025 salinity?
For a specific gravity of 1.025, you’d typically need around 35 grams of marine salt per liter of water.

Does kalkwasser lower salinity?
Kalkwasser can slightly raise salinity due to the calcium and carbonate ions it adds, but the effect is usually minimal.

Is a calcium reactor better than dosing?
The choice between a calcium reactor and dosing depends on your tank’s specific needs and your preferences. Both methods can be effective for maintaining calcium and alkalinity levels.

How long to wait between dosing calcium and alkalinity?
You can dose calcium and alkalinity simultaneously if you use a balanced two-part solution. Otherwise, you can wait a few minutes between dosing them.

Does kalkwasser lower phosphates?
Kalkwasser may help reduce phosphate levels in your tank over time, but it’s not a primary phosphate-removal method.

How long does kalkwasser take to work?
Kalkwasser can have immediate effects on pH and alkalinity, but its full impact on calcium levels may take some time to stabilize.

What is the best ratio for vinegar?
The best ratio for making kalkwasser is typically around 1 part kalkwasser powder to 2 parts vinegar by weight.

Can you use kalkwasser with 2 part?
Yes, you can use kalkwasser in combination with a two-part calcium and alkalinity supplementation method if needed.

How often do you need to clean a kalk reactor?
Cleaning frequency for a kalk reactor can vary, but it’s generally a good idea to clean it every few months to prevent clogs and maintain efficiency.

How is dosing done?
Dosing involves adding specific substances (e.g., calcium, alkalinity) to your aquarium in controlled amounts to maintain stable water parameters.

How do you make a Kalkwasser drip?
You can set up a kalkwasser drip by using a dosing pump or gravity drip system to slowly add the prepared kalkwasser solution to your tank over time.

Can you overdose kalkwasser?
Yes, you can overdose kalkwasser, which may lead to elevated pH, calcium, and alkalinity levels. Monitoring and testing are crucial to avoid overdosing.

Will high chlorine lower alkalinity?
High chlorine levels can potentially affect water chemistry, including alkalinity, but it’s not a common issue in reef tanks.

Is kalkwasser good?
Kalkwasser is a valuable tool for maintaining calcium and alkalinity levels in reef tanks, but it should be used judiciously and monitored carefully.

Does kalkwasser powder go bad?
Kalkwasser powder can degrade over time, especially if exposed to moisture or air. Store it in a dry, airtight container to prolong its shelf life.

What is fully saturated kalkwasser?
Fully saturated kalkwasser is a solution where no more calcium hydroxide can dissolve at a given temperature and salinity, resulting in a clear, stable solution.

What happens if I put too much Accu clear in my fish tank?
Overdosing Accu Clear, a water clarifier, can cause water cloudiness or other adverse effects. Follow the recommended dosage on the product label.

What is the pH of kalkwasser?
The pH of kalkwasser solution typically ranges between 11 and 12 when mixed to saturation.

What should I be dosing in my reef tank?
In a reef tank, you should typically dose calcium, alkalinity, and magnesium to maintain proper water chemistry and support coral growth.

How long does mixed kalkwasser last?
Mixed kalkwasser solution should be used relatively quickly, preferably within a day or two, to ensure its effectiveness.

How many dosing pumps do I need?
The number of dosing pumps you need depends on the specific elements you’re dosing and your tank’s requirements. Most reefkeepers use at least two pumps for calcium and alkalinity.

What is the flow rate of dosing pump?
Dosing pumps typically have adjustable flow rates, but they can range from a few milliliters per minute to several liters per hour.

Does dosing alkalinity raise pH?
Dosing alkalinity can have a minor impact on pH, typically raising it slightly, but the effect is generally not significant.

What are the symptoms of low magnesium in a reef tank?
Symptoms of low magnesium may include poor coral growth, decreased calcium and alkalinity stability, and problems with calcium carbonate precipitation.

Is too much magnesium bad for reef tank?
Excess magnesium can potentially cause issues in a reef tank, such as interfering with calcium and alkalinity balance. Maintaining a proper magnesium level is crucial.

Does kalkwasser affect calcium?
Kalkwasser primarily supplements calcium, helping to maintain its levels in a reef tank.

Is 7.8 pH OK for reef tank?
A pH of 7.8 is generally considered too low for a reef tank. Reef tanks typically aim for a pH range of 8.2-8.4.

Will a protein skimmer raise pH?
Protein skimmers can help remove organic waste, which may indirectly contribute to pH stability, but their primary function is not to raise pH.

Does raising pH raise alkalinity in reef tank?
Raising pH can have a minor effect on alkalinity, but it’s usually not a significant factor in maintaining alkalinity levels.
