Alk/ca consumption of new additions

[Flatlandreefer]

When adding new sps and lps to an established tank when do they start to consume calcium and alkalinity. Do they have a high demand initially or does their demand only start to become significant once they become established in the tank and start to create new growth?

It depends how bug the pieces are, but I would say it's extremely gradual. If you have a dosing pump it may be a few months before needing adjusting.
