Can someone please help me out!

I have a 90 gallon and i ran a tek 8 bulb with egg crate as a cover. I had basically sps some rics and zoos and green star polyps everything was fine. I upgraded my light the Elos Planet II. My sps starting dieing most of them burning from the tips so i thought ok light is burning them. WRONG! Make a long story short i eventually lost all my sps corals but my star polyps, zoos, rics are all fine i can't figure out what is the problem. I tried a digi and green milli that were already under MH lights before i put them in my tank and they were slowing starting to die also. I can't figure it out its been very frustrating because its been going on for like 2 months and i can't figure it out. Like i said most of the sps die from tips down anyone idea's would greating be appreciated. temp 79 s.g 1.024 nitrate ammonia 0 cal 400 alk 9 mag 1400

How are you keeping up your alk cal and mag. Do you dose these directly in the tank or the sump.
I lost a nice blue tip acro because I was dosing two part from the sump but one of the return lines was directly over the coral

i have a ca reactor and the return doesn't hit any of the corals directly my phosphates are 0.1 and my ph is 8.0 and at night 7.9 so that is ruled out also

i would still check out your alk.. high alk tends to burn out sps.

my phosphates are 0.1

That is WAY high for SPS. I can't say that's what killed them, but it's pretty high. Phosphate hinders calcium deposition, which has obvious implications for SPS.

Soft corals won't give a rip and might even like high phosphate.

+ 1 with Harry, SPS whiting or dying from tips down usually an indication of high Alk level.


- Use different Alk test kit (just to make sure)
- did you change salt brand lately?
- How old is your tank setup?
