I need some help my SPS corals are bleaching and my softies are not looking so hot as well. All other fish and inverts are doing fine.

I recently moved my 10g sump to the basement and swapped it out for a 55g sump and 10g fuge. I had a 45 gallon system which is now 90g total system volume. When I made the move I just added 45g of new salt water to the existing water. I carefully monitored salinity and temp before adding it.

The new system has to travel up 15ft vertically and 50ft horizontally. I am running a GenX Mak5 which is giving me over 600gph. I have a rather small bio load with 5 fish and my ASM G1X is in the new sump.

Here's the problem several of my SPS corals have begun to bleach. I have made no changes to the lighting only the flow and the total volume of water in the system. I am also running carbon and Rowaphos in two phosban reactors

Here are my water parameters
TDS in RO/DI water 0 ppm
Temp 80.8
PH - 7.93
KH - 7.2 dkh
Ca - 425
Mg - 1200
Salinity - 1.024
NH3 - .1ppm (mg/l)
NO3 - 0
NO2 - 0
PO4 - 0

According to these numbers everything should be perfect but there definately not.

ANY SUGGESTIONS? PLEASE HELP!
