Wow do you skim wetter i guess?Great pictures!
Not always easy to pinpoint the reason things goes sideway, last winter i almost lost all my montis and most of my acros were starting to stn, found out i was stripping no3 by cleaning the skimmer too often.
First time something like that happen to me in 16 years of reefing.
Yeah still running them and same par in the middle but running more blue now, instead of reducing blue to 80 for a few hours its just 100% all channels. Changed the schedule this time but lost my original one which i want to switch back to now. Orphek are kinda blue with all channels 100%. But that depends on what you classify as blue. My t5 unit is 50/50 coral plus blue plus which is quite white.Are you still running the Orphek? How high up? Did you ever test the par? I noticed on page 1 you mentioned 800 par…
tank looks great and glad to see it holding on and rebounding.
