heres a fun one: on the pictured 90gal, we just swapped out a PC system for 2 250w MHs and 4 65w actinics.. since this is my first such retrofit, im not sure what to expect in terms of algae and coral adjustment. any precautions i should be taking? also, how long should i wait before introducing the sps, now that the wimpy lights are gone?

pic was taken when corals were closed up.. one of the problems of only being able to visit the tank once a week for service.

thanks
