I never liked mixing any leather with sps, they do release toxin into the water which can trigger rtn. dkh seems to be okay if you are not on any probiotic system, if in any case you are or just started running pellets or zeovit then that could be a major part of your problem.
Also take a sample of your water to the lfs and get them to check your cal, dkh, and mag just to get a extra set of reading. This way there will be no mistakes on you readings.
Frag what ever is alive and tossed the rest, I have very little luck try to save dying sps colonies, but with that said I have done it before.
sorry for the lost, good luck.
