calcium level high

[sin]

I test my calcium level and it is high. It is 640ppm is this bad if so how can i get it to go down

Not sure how bad it is (though it doesn't look all that high to me..)
Only way to get it down would be water changes.

That is a little high, which means your ALK is low and could also affect your PH. They are all three related. What kind of salt do you use? Water change is about the only way to try to stabilize everything. I use Instant ocean salt and mine stays around 500. I've heard people who use reef crystal salt say they are at around 400. It's not good to just go out and change salt so you might want to get some other feedback. Just remember stability is key in saltwater aqauriums.

Are you using Oceanic Salt? If you are that is pretty normal for that salt, I switched back to IO because of the high Ca and low alk in Oceanic. A lot of people are mixing IO and Oceanic (50/50) seems to be the best of both worlds that way.
