OK OK a little more than 5

WOW thats a big water change!

Just something to think about, I'd probably do that much as a regular water change

I change 50g every other week, which is about 25%. I'd do more, but my bin is only 50g. I change about 75% in my biocube every two weeks.

Something to look forward to when I go bigger eh!

I think I will increase my amount changed from now on. My levels are always constant, and my lighting is all new with a 250w metal halide and 135w of PC and I have never really had a lot of LPS or leather growth...

Day after big water change no signs or improvment, I will do another large water change. Is there something that I am missing in this equation? Also I am noticing a brown algea creeping on my closed up zoas...

Just a thought, but if you have a new metal halide and you were running a less intense light you may have shocked your coral.

When we went from the PC light to our new metal halide things were not happy at first. we set the halide about 18 inches off the surface to start on only 4 hours a day. the corals closed up for almost a week then gradually started coming out and looking better.

we have since moved out halides down and are on for 6 hours of halide but it took a while for the corals to adjust.

I dont know if this is causing you issues but you may want to think about the timing of your issues in the tank.

That could be a possibility, when I switch to my new MH I to noticed it took a little time for things to get happy again. Leather and zoas especially can get light shocked really easy in my experience.
