Ok I've come to my breaking point.

I've been losing SPS for the last 2 months. Then Last night my 7 year old Hammer Coral is turning to mush and dieing as well.

I've checked everything
My water is good
Ammonia 0.0
Nitrites 0.0
Nitrates 0.0
Phosphates >0.03
PH 8.0 -> 8.4
Temp 79.0
SG 35 or 1.026
CA 430
ALk 8 DKH
MAG 1350

I have checked for AEFW and Red bugs
I have stopped the use of Zeovit
Installed a 40W UV sterilizer
I'm running 1L of GFO and 1L of Carbon
performing 2X 40G water changes a week

I've lost 95% of all SPS and now it appears as though my LPS are next.
Through out the this whole situation my Hammer has not extended it's polyps fully.
Fish inverts and Clams all seem unaffected

Looking for any suggestions

Thanks
Jason
