Seachem Laboratories Reef Kalkwasser - 2 Kilograms Information


Product Manuals & Documentation

Seachem Reef Kalkwasser is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. This calcium hydroxide meets or exceeds the purity of competing brands designated for reef use. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that are used in an automated dosing system that replaces evaporated water. Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly. However, its capacity to perform these functions is dependent on evaporation rate and CO2 concentration. If these two factors are insufficient you can provide additional calcium with Reef Advantage Calcium, Reef Complete, or Reef Calcium, and carbonate alkalinity with Reef Builder or Reef Carbonate (do not mix these directly with a kalkwasser solution). Reef Kalkwasser can also precipitate phosphates and impurities from the makeup water while maintaining a high pH which is important for proper calcification rates and for oxidizing various organics in reef aquaria. 2 Kg makes 2,600 L (664 gallons) of kalkwasser solution.

Great product

Experience Level: Intermediate


Comments: Easy to use and able to buy in large sizes. I use in all my makeup water. My system holds about 300 gallons and evaporates 3-5 gallons a day depending on humidity. I have a calcium reactor that needs set up but I will still add a small amount of kalk to makeup water. I believe in using Seachem products, have been using them for over 20 years.

Comments: I use 1/2cup of this product a week in my kalkwasser reactor (a must if you're serious about the health of a reef tank) and my pH & calcium levels are as steady as one could hope for. This is very simple to use if you have a kalkwasser reactor, but I wouldn't suggest this product to a beginner as overdosing could harm the health of one's system. I am giving it 4 stars because I haven't used the whole bottle yet, and am waiting for completion of product before I praise it further.

Comments: I use 2kg of this a year and it is great. The price is right. It does not clump up in my kalkstirrer, other brands with Mg did. I refill the stirer monthly, dose with a litermeter III and by it alone keeps Ca=400, Ph 8.4 in a 180g SPS + clam reef.

Comments: I am using this product to maintain Ph on a 125 mixed reef...It is super loaded and has a tendency to drop in Ph....This product mixes well and settles fast. I am using it in a 2.5 gal aquadoser. I just set it on the top of the hood to my tank and drip away....Corals are more colorful and "hairy" (SPS) and polyps are more extended...(LPS). Inexpensive, great product...the bigger 4 L has a lid that is a bugger to open, but that is overcome with continued use....

Comments: Maintains calcium levels, as advertised, but don't recommend for a large reef unless you have a high evaporation rate and lower calcium needs. Be careful not to overdose.
