sps help

[thechristalfamily1]

a few weeks ago I had a minuscule frag of Ice fire echinata that had no PE on it then in 3 days time it died. it did not turn white but just lost its color and then died. now my orange setosa is showing large white spots on the two highest tips. my parameters have been good but i have started adding more calcium to the tank because of all the sps growth that i have been experiencing. any advice?

+1, Parameters are normally the cause of most SPS deaths and then pests would be second. White tips on SPS can mean growth, when the white starts at the base it is usually a fatal sign.

alk-dont have a test kit for this
nit-0
Phos .5
Cal 460
Salinity 1.025

the weird thing is that i had 2 pieces of the same coral next to each other and one died while the other is thriving.
