Calcium And Phosphate Level

[mn1467]

Does High Calcium and High Phosphate levels harm fish?
The reason I asked is that I set up a coral only tank with no fish. I tried to recently add some fish and they died the next day. All levels are normal except for calcium and phosphates.

high high is your calcium. Fish don't seem to mind calcium from what i am aware of. :thinking:

i am doing small water changes every 2 days to try and get it down

what test kit are you using? that seems really out of the ordinary. Also what is your alk and ph levels?

 

[mn1467]

I think it is called red sea My LFS said it is one of the best to use. All other levels are normal

I guess I just purchased 2 bad fish. my luck
although the corals are doing fine

calcium 400- 450
alk 8-12 (9-11 for reef tanks)
PH 8.2- 8.4
If your calcium is that I would take an educated guess that your alk is high too. I would get a salifert calcium test and use it. Don't the red sea tests just give you normal or high test results. depending on what types of corals you have this can be detremental to there health.
