Two Little Fishies Kalkwasser

Dosing with Kalkwasser is an effective way to add calcium and alkalinity to your reef tank. Be sure to test and make sure your calcium and alkalinity levels are correct before beginning Kalkwasser dosing.

This is a calcium supplement mix. Our pure source of Calcium Hydroxide makes the ideal solution for replenishing calcium and maintaining alkalinity for corals, clams, and calcareous algae that build skeletons of calcium carbonate. It also helps maintain pH, precipitates phosphates, and enhances protein skimming. It is available in 500k 1 lb bottle and 2 kg.

Using Kalkwasser (Calcium Hydroxide)
Kalkwasser is the easiest method to maintain calcium and alkalinity levels in a reef aquarium not to mention low cost. With a few different methods to implement it, if your corals are growing and you need to add calcium and alkalinity, you will more than likely find multiple benefits from using kalkwasser. Being the only way to add calcium and alkalinity from a single solution along with helping elevate the pH of your aquarium to helping purify your ATO water even further, there are plenty of reasons to add kalkwasser to your ATO reservoir or set up a Kalk reactor or drip system. By far the most common application for kalkwasser is by adding it to your tanks top off reservoir and then relying on the auto top off system to deliver small amounts of saturated kalkwasser solution throughout the day. 
 
We suggest using Two Littel Fishies Kalkwasser as it is the purist available along with the AquaLife Simple Science 3 part for general adjustments to elevate and balance your aquariums parameters (calcium, alkalinity, and magnesium).

How to Use Kalkwasser with an ATO System
Step 1. Test and adjust your aquariums calcium, alkalinity, and magnesium levels using AquaLife Simple Science part a Magnesium, part B Calcium, and part C alkalinity.

Step 2. Start by establishing the proper amount of kalkwasser to mix into your aquariums top off water reservoir. 
Low Demand - 1/2 teaspoon per gallon of top off water
Medium Demand - 1 teaspoon per gallon of top off water
High Demand - 1 1/2 teaspoons per gallon of top off water

Step 3. With RODI water fill your top off reservoir & mix in the proper amount of kalkwasser then allow the solution to settle for 30 minutes before using.

DO NOT OVERMIX: Excess mixing and air contact will decrease the potency of kalkwasser.

Step 4. Place your ATO systems pump or intake line is place 1/2" to 1" above the base of your reservoir, ensuring only the clear slurry is being dosed. 

Step 5. Activate your ATO and monitor the pH of your aquarium as the kalkwasser solution is being dosed, not exceeding increases of 0.20 pH. Your ATO should be pumping water into a high flow area of your sump or display tank to help prevent precipitation. Adding kalkwasser too fast may result in precipitation rendering it ineffective. 

Step 6. Monitor your aquariums calcium and alkalinity daily, adjusting the strength of the kalkwasser solution in your top off reservoir as necessary. 
 
Note: A pH controller can be used to prevent pH spikes and overdosing.
