my sps corals are experiencing moderate growth and and noticable but pale coloration.. calcium and alk a little low at 380-400ppm and 2.98-3 meq/l respectively. i am running 1-110w true actinic,1-110w 50/50 (vho's), and 2 hamilton 400w 10k Halides. i have a brand new never fired hamilton 10k that i would like to trade with someone for a new or barely used 14k to see if the coloration will become a little more noticable.. any thoughts ? oh yeah vhos on for 12 hrs.. and halides on for approx 6 hrs
