"Sandy" water safe for coral?

[Waters]

I am in the process of upgrading tanks. The live rock, coral, and fish have all been in temporary containers while I completed the plumbing and got the new tank ready (for 4 days now). I finally have the live rock back in the new tank. I only have roughly 75% of the water in (currently making new RO/DI water) but it is still pretty cloudy from the live sand. Is it safe to add the coral and fish back in at this point? It has to be better than the containers they are in now....I was just concerned about the sand (specifically for the coral)?

I am not sure, seems like the floating sediment would land on the coral causing them irritation. Maybe if you blow them off frequently. Even still not sure if it is a good idea. Anyone?
