I would never put any inverts into a cycling tank.
They may not survive the ammonia peak.

I hear your concern. The tank has been cycling for three weeks with live
sand and live rock. This mornings test yield sg 1.021, ph 8.4, nitrite
0, ammonia 0, nitrate 0. My problems are the algae and calcium 330 mg/l
level. Is 330 acceptable?

I wouldn't put an emerald in an aquarium where there will be small fish.
Emeralds get huge and will happily eat a fish. The one that i used to
have ate two small maroon clowns that I had. Just something else to
think about.

I always considered them to be mainly herbivores and occasional scavenger.
Never considered emerald crabs to be an active predator hunting for a live fish.

How sure are you, he did actively hunt for them, and not that they died on
their own and the crab just helped himself to a piece of dead fish?

I saw him catch the smaller of the two. I stopped him from killing the
maroon. When i woke up the next morning the smaller maroon was
completely gone. Within a week the larger was gone. I found his dead
body in the crabs mouth. I'm 99.9% sure he killed both of them.

Was maroon fully healthy or was it weak or dying already?
This is interesting observation.

Why haven't you separated them both to different tanks
or at least to the sump??

Within a week the larger was gone. I found his dead body
in the crabs mouth. I'm 99.9% sure he killed both of them.

Dead fish in his mouth confirms he is a scavenger.
Does not prove he attacked live fish.

Here is what I found about emerald crabs on reefcentral.com:

"Emerald crabs are often misidentified, and while some
predominantly eat algae, others don't." - Ron Shimek
