I think I found out what the problem is. I believe it's NSHP......I guess I just assumed there was sufficient amts of Ca in the Nekton-Rep. I also didn't realize that consuming vits would interfere with Ca uptake (guess I'm gettin a lil mentally lazy). Good thing I got some powdered Ca (crushed cuttlebone). I'll see if that does the trick along with some sun worshiping sessions now that it's June. Thanks again for the heads up.
