    Cool zeke

    In my topoff water I do let it sit for a day but sometimes it does tend to stay a bit milky. I've never had a problem in the 3 years I've used it.Just either try to drip it or if your using it with a float switch I always cut back on the amount of KALK powder I put in. I use 1 level teaspoon per 5 g. You could use a pail[5g] and put a valve on it so when you mix up a batch let it sit then you can open the valve and let the clearish water out into your container. try not to use that crust/film you see on top.

    We haven't set up our automatic top up yet. I put 2 or 3 tablespoons of kalk powder in a gallon jug and top up with RO water. I shake and let sit. After sitting 15 to 20 minutes, I pour the lighter liquid (usually still milky) into another gallon jug that I have set up to drip into my sump. I then refill the orginial gallon jug with more RO water. When the kalk water is not milky after shaking, I then add more kalk powder. This way I don't get the crust/film that Johnny mentioned on the top. This crust is caused by a reaction of the kalk water with air.

    I drip into the sump compartment that the tank water enters so it is well mixed before it gets to a pump. I have read that some people dripped near the pump and ended up with kalk deposits in their pump.

    I have a Nilsen style kalk reactor that feeds my tank through the automatic top-off.

    Hardly any maintenance. I add about 1 to 2 spoons of kalk to the reactor per week. The reactor has a timer that mixes the limewater every 6 hours for 1 minute.
