Calcium Chloride--I've used it several times in RAS and saltwater systems when raising corals,inverts, and fish with a high calcium need. I wouldn't be worried about raising the pH at 7.8 (depending of course on what time of day it was tested, just before sunrise is the most critical time to test). Ag lime won't push the pH above 8.5 or so, which I would be fine with. I typically shoot for alkalinity around 100-150 mg/L and calcium at around 100 mg/L.
Possible---Yes
