Too much calcium?

Here are my tank peramiters:
Ammonia: 0
Nitrites: 0
Nitrates: 5.0
pH: 8.3
Salinity: 1.023
Phosphates: 0.5
dKH: 10
Copper: 0
Calcium: 500
65 gallon (36"x18"x 24"). Tank just cycled. Live sand and 70# live rock. Running for 4 weeks. Hermits & Turbos are good. Have a 10 gallon reef that has been running for 4 months. All perameters are identical except for calcium and salinity. Calcium in 10 gallon is 400 and salinity is 1.022.
Took a mushroom & hammer and put it in the 65 gallon. Hammer does spread but not as much as it use to. Mushroom (rhodactis?) does not want to grow or spread as much as it was in the 10 gallon.
What do you think?
Thanks in advance for any help.

I think your salinity is low and your phosphates are a bit high.
and your calcium is high too, could be throwing your alk out of whack.

Have phosban and some type of phosban filter in the refugium. Have been trying to lower for over a week. Not much lowering though. Will keep trying to bring it down. But, why happy in one location and not the other?
