Just wondering if the tunze kalk reactor is worth the investment? Or is there a better option? I currently put it in my ATO container with the pump off the bottom to not get the clumps. But I know kalk isn't good for your pumps over time. And I wonder if there is a better way. I'd rather not use a kalk reactor bc I have a carbon and gfo dual reactor and it takes up too much space. So I saw the tunze brand one that can sit in my bucket with RO and pump and not take up space in sump.
