I wanted to know what is the best way to lower calcium levels? mine are higher then 450 also what happens when it is too high? I did a 15% water change in my 55gal. ANy ideas? Thanks

If it's just a little over 450 and your alk is inline with that then I would think you're probably fine. Did you test your alk? Are you using any additives? Out of curiosity, what brand of salt mix do you use? I use Oceanic it's usually at the high end of the range for CA.

Water changes

water changes may not help if there salt mix has high alk to start with. I know a guy who has his over 500 and his tank is fine right now. In no way am I saying to run your tank over 500. I would not panic at this time, how does every thing look?
It seems that Ocieanic salt has a real high alk level right out of the bucket. I use it and do not have that problem, wish I did becasue I can't get mine above 380 for some reason...
