How long to wait after dosing Soda ash to dose calcium?

[Miami Reef]

I am setting up my dosing pumps to automatically dose every hour or every 2 hours. How long do I space out the Soda Ash to Calcium Carbonate for my relatively small sump size?

Calcium chloride, right?

As soon as the alk supplement disperses, the calcium is fine to add. 10 minutes in many cases is fine.

You just do not want the two concentrated clouds to mix before dispersing.

Thank you! Yes I meant calcium chloride. I had a chemistry class today and I got confused haha.

No problem.

Some (undesirable) products are calcium carbonate, so I just wanted to be sure.
