Loosing large SPS colonies

[Werbo]

So it's been a week. I was out of town and I am happy to report the large turaki colony looks better. By better I mean the tissue appears thicker and healthier. The tips that have died now have algae and it is slowly populating the dead areas.

Picked up a chiller (thanks Ryan). Bought a API nitrate test kit. I'm somewhere between 2-5 ppm for NO3. So not to bad but could be better. Test PO4 tomorrow and Alk/Ca.

Fwiw, tips seem to recover faster if you nip the dead ends off. NO3 looks good to me! I'd be more concerned about PO4 and alkalinity if NO3 is only in the 5 ppm range.
