Having some trouble figuring out how one would set up a kalk stirrer below the sump. It seems all? of the stirrers out there are configured as inline with the ATO and depend on overflow/gravity drainage into the sump. In my setup, I would need to have it below the sump but can’t figure out what the best way of setting this up would be. Overflow into another container and a second dose pump pulling from this overflow container into the tank? Seems overly complicated
