My tank has been up for about 8 months. All my corals (that aren't SPS) are doing great! Hammers, zoas, chalace, favia, torch, acans, lobo, avelopora, and a duncan are all doing great. But every time I add an SPS coral it dies fairly quickly. I added a purple stylo that made it about a month. Two montis started dieing pretty much as soon as I put them in. And two digis died in a week or two. I feel like my parameters are pretty on point and stable so I'm at a loss for what I am doing wrong. What could it be? What should I do? How can I keep SPS alive? What am I doing wrong? Any ideas or suggestions are welcome. Am I just unlucky?
Parameters:
Salinity: 35ppt
Nitrate: 2ppm
Phosphate: .02ppm
Alkalinity: 8.2
Calcium: 410
Magnesium: 1500
I test nitrate and phosphate weekly and alkalinity about 2x per week (recently started dosing with a doser). My alkalinity has been between 8 and 8.5 for months.
