is 600ppm calcium ok?

[Wolf]

my tank hovers at 600ppm calcium and has for about 6 months now without
adding ANY Calc supplement, unless superbuffer adds calc. it kept it near
450 using turbocalc until i got a bag of argonite to finish up my homemade
refugium. do i need to do some water changes or will that be ok? its my
understanding that it can only clog pumps etc, and there has been no sign of
that.

Are you sure that your test kit is OK?
I'm not sure but I think that if the Ca was so high it would lead to
pecipitation of Ca and Alkalinity on the glass, pumps, heaters...

I was wondering the same. My tank hovers somewhere up there as well, and
this also occured after adding a fuge to the system.

May depend on what creatures you have as well. I had too-high Ca for awhile,
and my green star polyps wouldn't fully extend. I slowly reduced Ca to
NSW levels over time, and the mat of polyps happily recovered.

400-450 is much better than 600, all around.

Mine is in the 600 range as well. For me it isn't the test kit. I've
checked it with 3. For me I believe it is a combination of using
aragonite deep sand bed and using Oceanic salt which is known to have a
high Ca and Mg content. It hasn't been a problem except that my dKh
was slightly low and I had to buffer to get it up to 11.
