kalkwasser

I did both a Ca reactor and a kalk reactor, and when I get the new tank ready I will be running the same.

ya find this better than bio-pellets

Completely separate technologies. Biopellets don't supplement Ca/alk.

so technically i could run all three?

Ya, although I disagree with Steve. I think if you need to run a Ca reactor AND a kalk reactor, neither of them is operating or sized properly. You should need one or the other.
Or, if you use a top off reservoir, you can simply mix the kalk into that.

and I thinks you need to read up on how each one works again and you'll remember why we used both and why I still like them in tandem

don't forget I don't really run a Kalk reactor but rather an inline top off water reactor, it looks like a reactor and mixes like a reactor but only adds to the tank during top off. so I guess in a way I do agree with Brad, I would never run both a true Ca and Kalk reactors, but I will run a Ca reactor and use kalk in make up water (saturated level)

they both supplement Ca, alk, but in totally different ways which both ways have advantages for your tank. kalk will bind phosphates where a Ca reactor will release phosphates as one example.

I use a calcium reactor then add kalkwasser to ato with a power head. it helps keep my ca and alk a bit higher but for the most part I use it to raise my ph.

That statement kind of suggests I ever read up on it -lol

Bio pellets are for reducing nitrate and phosphate nothing to do with calcium and alk

Kalk is an excellent way to maintain calcium and alkalinity in a balanced way. The major advantage is that it also increases PH.

Wit that said, there is only so much kalk you can dose when you saturate your top-off water with kalk. If you have a heavily stocked tank (lots of corals) it won't be enough.

You can alternatively blow a fan across the water surface of your tank to evaporate more water so that you can top-off even more but it may still not be enough evaporation to keep up with demand.

I know what some with heavily stocked tanks top-off with kalk and also use a dosing pump. The reason for this is the increase in PH from kalk.
