What could be keeping my calcium levels elevated??

12/24/04- 800 (ppm)
12/26/04- 750
12/29/04- 750
1/2/05- 750
1/6/05- 700
1/11/05- 700

1/31/05- 650
2/13/05- 650
3/4/05- 700
4/8/05- 600
5/5/05- 550
5/11/05- 550
5/30/05- 550
6/5/05- 550
6/6/05- 550
7/7/05- 550


I use IO salt and do about 4 - 5g water changes /month (135g total tank volume). I am only adding lugols, strontium on a weekly basis.

I have coraline growing steadily, finally!! And have added the calcerous like macro algea, it was white (low calcium) when I got it now it is turning green.

Dunno, everything in the tank looks happy.

A bad test kit or a bad batch of salt. What's the Alkalinity?

 

[silly34]

Test kit is new, and I buy salt frequently and from different shops. Alk has been 2.75 - 3 ppm

what is a good level for calcium to be at?

 

[sediener]

It looks to me like it is slowly coming down from an overdose in December. It is so slow since your WCs are only 4% of the system volume... maybe do a few larger waterchanges of 20% or so?

Most reefers shoot for the 400 to 450 ppm range (IIRC natural seawater is generally around 420 ppm).

They'll come down if you have SPS or Halimeda growing in the tank. The Alk will get lower as well though - you have to keep an eye on Alk.
