Few days ago I just finished the kalkwasser mixer .
It looks like Deltec but this became improved by me .
I installed much better stepper motor controller with electronic adjustment from 0.5 rpm to 9.5 rpm and LCD display .
For now I made two of them for 250 gal tank and for 500 gal tank .
This one on picture is for 250 gal tank , dimensions : support 6"x6" , tube 5" OD , height 21" .
I almost finish copying of calcium reactor too , this is really nice toy
, as example I used deltec PF 500 , I will make some pictures tomorrow .
