I want to start dripping kalk, however, I just don't have the space under the stand for another container. I currently have a single switch autotopoff system and would like to add kalk into the topoff bucket. I know it's a bad idea because if the switch gets stuck or skimmer goes nuts, I'll have a kalk overdose. So what i was thinking is to upgrade my autotopoff system to include an additional float switch for cutoff in case something goes wrong. Has anyone successfully dosed kalk this way. Any suggestions or comments would be greatly appreciated.
