Can't keep SPS alive

[One_Divided]

I would definately rule out your cal and alk levels as being a problem. Untill I had calcium reactor, I would have to fight to get my calcium even as high as 320. alk would be 6-7dkh, sps were always healthy and grew anyways.

I would maybe question that there might be something in the sandbed. It could be a lot of things. Phosphates, metals, who knows. I'd start doing some more unusual tests.
