I had a tank crash in May which wiped out my SPS. My water parameters were terrible then (high Nitrate), but I had good growth. I have since restarted the tank, and added more frags. Water parameters are not great (need to measure and repost) but are better than they were before the crash. However growth is almost non-existent. I have 2 birdsnest frags which grew at first, but have since slowed down. I have about 8 acropora frags, I only lost one since restarting, but have had no growth from the others. I have about 40ppb Phosphate (Hanna ultra low), 5ppm Nitrate, Calcium around 400ppm and about 9 dKH. Something is using lots of calcium, as I am adding lots and it (and Alk) is falling fast, most likely a large squamosa I added, as none of my coral is larger than frag sized yet.
Could this be because I haven't had the tank running long enough? Or is PO4 to blame? I know it isn't the lights (DIY LED) because I had them before the crash.
I've also noticed almost no corraline growth (a good thing for me) since the crash. Before the crash, it was so out of control I had trouble seeing inside the tank even scraping weekly.
I have no soft corals that I didn't have before the crash, and lost most of the few I did have.
