I have been looking around, and i haven't been able to find out what exactly a kalk reactor is and how it works.
thanks

It's just a device that mixes kalk into fresh water automatically, for dosing into the tank. Usually they have a fresh water reserve or perhaps are hooked to an RO-DI unit, with some sort of stirring device that turns on automatically. I decided to dose limewater that's mixed by hand, since it's purer that way.

The thing that i don't understand is how to make limewater, and whether or not you need an auto top off to dose the limewater...
I usually add RODI water to the tank once a day by hand. Would it be ok to just add my ~2 quarts of water (w/ kalk) to the tank all at once or does it have to be slowly added? I make my RODI water 5 gallons at a time...
Thanks again

I do my kalk top offs slowly dripped in over night. I personally would not recommend dumping kalkwasser in straight. I used to do that. I ended up supersaturating my water to the point where I had white snow in my tank. That did not harm the coral, however. The biggest problem for me was that the kalk ended up coating the inside of my plumbing. I was forced to disconnect the sump from my tank and to run the plumbing with vinegar instead of water. Once the vinegar ran through my lines, all of the built up kalk washed into my sump like potato chips. I am debating adding a kalk reactor, but, it is not really hard to slowly drip it in over night. So, I am not sure it is worth the expense.

Dumping the kalk in fast could easily cause a PH spike, and harm coral/fish. Most people add it slowly. Saturated kalk has a PH of around 12

That article discusses dosing limewater. I use a peristaltic pump and an autotopoff controller.

Why not just drip it in with a float valve and a bucket, and let gravity and evaporation add it in?

Float valves have a reputation for sticking. I wouldn't trust one.

Would a top off system from autotopoff.com work for dosing limewater??

If it allows a slow drip, it should be fine. I don't have any experience with the autotopoff.com products, so I can't help much there.
