    A Beautiful place!
    Howzit Ocean, I bought a Reeftek kalkwasser from Eco-aquatics with a pump in a closed loop system. The pump runs off a timer and comes on every 3 hours for 1 minute - mixing the kalkwasser with the RO water.
    When the water level drops(due to evaporation) and the float switch activates the RO pump, it pumps the RO through the kalkwasser and drips the clear calcium enriched water into your tank. Hope this helps.:wave2:

    The calcium dissolves into the water, and remains dissolved even when the water is clear. the correct way to go about this is to stir/shake the solution well, then let it stand for a few hours to allow the solids to fall out of suspension, and to then carefully pour/siphon the clear liquid into a second container and to then use only the clear liquid in the dripping device.

    Once dissolved, you don't need to mix/keep the water moving.

    what i do is take 4 tsp of kalkwasser throw it into ro drum(25l), shake well and place pump from auto top up in drum to suck upper layer out, when water evapurates.
    don't have $$$ for kalkstirrer, and it helps allot in my system

    Suggestion: dissolve it with vinegar, it helps dissolving it into the water column.

    To those who don't know what the heck we are talking about.

    Here is a quote from Anthony Calfo's The Book of Coral Propagation, page 185.

    I actually don't like kalk slurries for most hobbyists. Too much can go wrong and you can end up with a Carbonate snowstorm. Putting the slurry directly into the main tank can cause precipitate to fall on corals and burn them. Putting the slurry into a sump can cause abiotic precipitation and ruin heaters and pumps.

    For folks in the states, I have other reasons for not liking the slurry method. I won't do this and it isn't the pH that I'm worried about. Kalkwasser has impurities like anything else does. If you are saving money by using Pickling Lime I would have concerns about the heavy metals you are adding to your tank. Kalk has the ability to remove heavy metals from solution. Server error! That's obviously a good thing but that only works with the supersaturation method. With the Slurry method you are pouring the pollutants right into the system.

    Why do the pollutants concern me? Here's why....Most Calcium Hydroxide that you buy is coming from my back yard. Well it's an hour and a half away but I've been there many times. It's coming from theMississippi Lime Company in Ste. Genevieve, Missouri. It's an awesome place if you are into history as it is the only original French Colonial Village intact in America. If you are into history like me it's worth a visit. Unfortunately, the lead poisoning effects of the Doe Run smelter has been found in Doe Run, Herculaneum, Leadington, Ironton, Ste. Genevieve, etc. I.e. Cities that are miles apart. The EPA forced the Doe Run Corporation to buy out a couple of whole towns due to lead poisoning. BTW....they also smelt copper. Give that one a thought if you have any invertebrates in your tank. I'm not going into any more details to protect the owners of this board. However, a Google of "Doe Run + EPA" will shed some light on the subject.

    The thing that goes through my mind is, once a heavy metal like lead or copper is introduced into my system, how do I get it out???

    Kalkwasser can be confusing to use at first, but it doesn't have to be.

    Even though I'm not a famous reefing author, you can see from my previous post that I'm not a fan of the slurry method. That's my opinion. Other's may disagree. But Calcium Hydroxide additions are easily the most inexpensive way of maintaining Calcium and Alkalinity once your system is balanced. I've explained why I prefer the supersaturation method recommended by Reef Maniac (at least for Americans getting their Kalkwasser from Missouri).

    Excellent reply, Mantisfreak. I use both methods (slurry and supersaturation) and both work for me.

    Not sure where South Africa gets it Calcuim Hydroxide supply from, but I would think heavy metal poisoning would still be a concern wherever it came from.

    Need to see if there is any info on the local supply
