I think this build is due for a little update, aside from pics.
As mentionned in previous post, i went throught a difficult period from Feb to May-June, i lost a few (several) acros and my elegance. During that time i focused on keeping everything stable, i kept using the AF salt (Pro bio and Reef salt) even if i considered going back to my previous salt.
I just completed a 3week Interceptor treatment after i found some white bugs living on my acros (in the polyps!!)
I have seen a drastic improvement in my coral since then, polyp extension is better than ever, the growth and color are back. I can almost see daily growth (i dream!!). But seriously, polyps, colors, growth is amazing. From March to May, everything was pretty much on hold, growth was none, colors were not brilliant.
My tank is now blooming as you can see on my few post before this one!

FINALLY! I guess difficult period are part of the hobby, i'm still unsure what made my tank go south like this, the sum of the changes i made around chrismass, the bugs on my acro... who knows! My mood was fonction of my tank for a while... wife and kids were worried
Aside from AF reef salt, i slowly increase the AVBE from AF, from 1 drop every other day, i'm at 2 drops now. I jsut started dosing their Alk-Ca-Mg and component strong.
I dediced a couple of month ago to slowly siphon my sand and go bare bottom, i really love the sand, but i saw it was time consuming when my tank was not doing good and i could not keep up with its maintenance, it will also give me more space for my monti collection, chalice, favia and others.... more room for coral is always good. I'm almost done siphonning all the sand.
Fish wise, all fish are back in DT, i had half the fish in QT for a long period of time, but could not catch the remaining fishes... since my corals were doing a lot better, i did not want to remove rocks and stress coral, i sent all of my QT-fish in DT... I just hope for the best! I lost several fish: 3 vanderbuild chromis, labouti wrasse, red mandarin, watchman goby. All my remaining fish seems healthy... but all my dead fish looked healthy 24h before i found them dead...
