I haven't done it yet, it's just an idea in my head. Just wondering if other people have done it or though about it too. Thanks Deanos.
Just thinking of other ways to dose automatically without breaking the bank. I know Cal reactor is expensive.
Are you refering to baking soda and dow flake for the powders? Not sure how well this would mix in the sump. Also you would need to figure out how much alk/cal is being added with each dosage. I think you would need pretty high flow for it to mix properly.
