Red Sea's "Marine Success Buff" requires very small doses?

I just bought Red Sea's "Marine Success Buff" for my 40 gal reef tank
(it was what was available at a local store).

Looking at the dosage directions, it says at 5ml per 60 gallons (240
liters) per *week*. For my 40 gal tank, that would translate to about
1.1 ml per day. Ie. just a few drops.

Doesn't that seem like an awfully small amount? I remember using Kent's
Pro DKh (or some name like that) and it was more like a few ml per day.
