Kalk Auto Top Off

I am going to use a 5 gallon bucket and a 3.5gph pump to auto top off my 75gallon tank. I plan to attach the float in my sump which is going to turn on my aqualifter pump. However, I would like to dose Kalk as well. I was planning to mix the Kalk and RO water and then put it in the 5g bucket. (The pump would be a few inches from the bottom of the bucket). Over a couple of days, would the Kalk stay suspended in the water? I was thinking that it would just settle to the bottom after a few hour and do nothing. Should I add another powerhead to the bucket, set on a timer to stir the Kalk with the water? When this is happening the timer wouldnt allow any water to be pumped into the tank. This is a $200 version of what I want to do but I can do it for less than half that. (www.drsfostersmith.com)

absolutely and great post. kalk reactors are simple and EXTREMELY EFFECTIVE. You have the basic idea down pat. Hook your auto top-off pump to one timer and your power head to another timer so that they don't come on at the same time or for a few hours after stirring. Coralife strip timers are good for this as when one outlet is "live" th others are not.

JMO, but I think you would be far better off spending the extra money to invest in buying or better yet, building a Kalk reactor as opposed to mixing the kalk in the open bucket. In most conventional kalkwasser drip systems, the kalk reacts with CO2 in the atmosphere and precipitates out into calcium carbonate which is pretty much useless. Having the fresh water enter the reactor, then mix with the Kalk within the sealed unit eliminates this issue. There are a good number of DIY manuals peppered throughout the Web on constructing a good Kalk Reactor at a reasonable cost.

Take pride in what you do, for it is a reflection of who you are.
