RTN Acro Quarentine

Had a huge die off on 3 frags of Acropora Formosa "Staghorn".
Frags were in a 10 gallon quarentine tank and had been treated by another reefer with interceptor, for red bug. Die off happened overnight with water turning milky white. Q tank has just a bubbler for filtration with sponge from sump. I decided to get everything, about 10 frags into my 180 gallon tank right away to have more water moving around the frags. A Millepora, also from Q tank, is now showing skeleton at its base.

What could have caused such a huge die off? Lighting was 400w MH in first display. My Q tank has 96w power compacts. Is a one month quarentine for new frags a good practice for SPS or did it result in the die off?

Just a quick guess but I think you killed them in your quarentine with using just a bubbler. SPS especially acros require high water flow to remove waste and bring in nutrients. Also, water parameters of the quartentine tank would help.

Water was put in Q tank from main display the night before. Parms: Temp 78F, SG 1.025, PH 8.22, Mag 1125, Cal 430, Alk 2.74. You think just a small powerhead would help in 10 gallon Q tank? Did a 50% water change in Q tank. Water still a bit milky, I'll retest tonight.

Yes, acros require alot of flow. I would take two small power heads and point them at each other to make chaeotic flow in the 10. Watch your alk demand also.
