How big is your tank??
How does this work for you?
I'm dosing for about 1 month now with esv Powder Kalk...It doesn't seem to be doing the job both calcium and alk have dropped...I followed the instuctions and now I've doubled the instructions at 2 teaspoons to 4 teaspoons,just yesterday...
So thought about building a Kalk reactor as long as someone has done this with success...Meaning they don't dose A&B or have a calcium reactor...Is this you also??

You need to read up more on the links Deanos had posted regarding what Kalk can do for you. Otherwise you are wasting time..

I know it precips phosphates but not on a scale big enough for me to really notice...
I look through all his started threads and can't find it...Do you know exactly what the name is????

You cant just double the teaspoons. THere is a saturation point where adding more kalk doesn't do anything. You can dissolve more kalk by using vinegar.

If your using it as a top-off then you can try and increase evaporation with a fan. Keep an eye on your pH. GL.

Just dosing... The doser I have has only 2 dosing tubes.. Not top off unit...
With the reactor does that powder after the mix go into the sump, when dosed..
