I had this in another forum but got no response. Just trying to plan this out so please give me your thoughts.......I'm trying to get everything together to change from 2 part to a Ca reactor and kalk stirrer. I've got my Ca reactor along with everything to run it. Now I'm looking at Kalk stirrer's. I've been told to get the Aquamedic KS 1000. So I'm trying to figure out how to integrate the stirrer into the system. I have an apex and would like to control this via the PH. Also have a tunze ATO. So now I just want to know how to integrate everything. Please if you have part number and where to buy things post the web page. Thanks.
