Wow over 200 posts now, this thread is getting big. Just another up date. I have reduced my MH time from 8 hours to 5 hours. I have also removed my GFO reactor from my sump to increase nutrients a little more, still 0 no2 and 0 po4. I now only have my skimmer running the system. I may run a BB fuge if my no3 gets to high, no sand this time. Sps growth is still good, better I think since stopping vodka. My glass is staying cleaner for longer. I am still fighting CCA in my sand and a little on the LR, but its is under control for now. Still no major changes in sps color. I go a new cool acro frag that has some cool multi colors I will try to get a good pic of it. I see a slight hint of green in my RP. My ORA bottle brush lost all its blue in the tips, great PE though. I am still feeding the same until I see a need to reduce feeding. Going to give it some time and see if anything improves. Question. I am going to get a 175w SE MH. Does anyone think that will be better to use than my 250w? I will be using a Phoenix 14k in in most likely.
