Too much Ca

[Jimboaf]

Ok so I have had my tank up and running for about two months now and I have started to add some corals. I just bought a bunch of new test kits to test for Cal and KH. I tested last night and this is what I got:

Nitrate - 0 ppm
Nitrite - 0 ppm
Ammonia - 0 ppm
:death: Cal - 600 ppm :death:
KH - 143 ppm or 8 dKH
pH - 8.0
Salinity - 1.023

Everything seems to be fine except for the Ca, I know that is high but everything in the tank seems to be doing great, and all the other levels are perfect. Any help will be greatly appreciated.

Are u dosing calcium or kalk? What kind of test kits?

 

[Jimboaf]

Nope I am not dosing calcium thats why I dont know why its so high, and the kits are API liquid tests

 

[Cheeser]

Strange, could be a bad test kit. I'm curious to see what others have to say.

Make sure you are following the directions exactly. The calcium tests are a pain, especially API. If you aren't dosing anything and only doing water changes, it probably isn't really that high. What kind of salt mix are you using?

 

[Jimboaf]

I use instant Ocean Sea Salt

What are you using to test your salinity? If everything looks fine in the tank, I wouldn't worry about it too much, but I would run that test a few more times and maybe get a different calcium test to compare with. Will your LFS test your water for you? Mine will only test for the basics.

+1 on verifying with another test kit... I'm using IO salt and my Calcium is at around 330. I've ran the (red sea) test about 8 times over the course of the last few days so I'm going to pick up a different test kit this weekend to see if it's really that low.
