Calcium level ok to add coral?

[saixiong08]

I don't have any corals in my tank now, but plan on getting some this weekend. I tested my water and the calcium is at 365 ppm. Will this be ok? I am currently using instant ocean salt. Doing 10-15% water change weekly. Plan on getting some Zoas first.

I've kept zoas at 365 ppm calcium before but I'd recommend bringing it back up to 420 ppm. They don't consume/use a lot of a calcium like corals with a hard a skeleton but calcium may still play a pivotal role in other biological processes. Sticking close to normal saltwater parameters or slightly above will yield you better results versus being slightly below normal salt water parameters.

What are the other parameters? Calcium is important but others are more so.
