Wow, so boy have things changed since April. As some of you know I have gone through almost 9 months of cyano & nutrient hell in general. Ironically enough, the acros I had over the last couple months had better color during nutrient times than now, but that's another story.
In April I took in some frags and colonies for a buddy breaking down a tank, and had an alk drop issue. I tested for weeks after adding things and it never budged. One day it went from the stable 8.6-9 down to 6.5.... I didn't realize until things started looking strange. I lost several colonies within days, some receded down to about nothing but survived. Those are now growing and thriving since then.
I tried chemi-clean in may, and it got rid of everything right away from rocks and sand. Months later, cyano slowly started coming back on the sand. I was going through 2 cups of BRS high capacity GFO every week at one point and I could never get my PO4 close to .02-.03. I'd put in new GFO, get it from .1 down to .03, then back up again. Almost got to the point where I tore this tank down. At one point, probably May-June I realized I had red bugs on all of my acros. Some of them were infested beyond belief although we never lost anything. I did the interceptor treatment, and then got an algae bloom because of the pod die off, etc... more nutrients, more algae. ARGH! Literally, at the point of throwing in the towel..... until one day..
On the advice of a local reefer (thanks mark) I decided to pull out my skimmer, and give it a nice RO cleaning. I literally pulled everything apart, toothbrushed it, got everything sparkly clean and realized that my bubble plate looked strange. The output of my pump was going directly into the little holes in the plate and not onto a solid piece of the plate.... 'DOH!!!!!!! Could this be my problem all along? My skimmer wasn't undersized as some thought, but just not working even close to capacity? I fixed the plate, reinstallled it, and for the next month it was pulling out 1-2G of tea skimmate (on dry setting) every WEEK! Within a month the cyano, hair algae, was all gone. My rock started coraline'ing up, and everything looked 100x better. Between polyp extension, growth, etc.
So today my tank is clean, looks great, and we have added a LOT of acros since then. I have gone from dosing alk\calc once a day via RKL + BRS doser to dosing both hourly to increase stability. Alk & Calc are stable, NO3, PO4 are low, and everything is happy... The new GFO we switched to works much better than the BRS stuff and lasts almost a month, and if not could be more even. Everything that had just bland colors are actually in the last two weeks starting to color up.... finally, I think we're in a good place. Now just to leave it alone and let things grow.
Mother of Pearl getting color back.
Oregon Tort. Couple branches were lost in the alk swing, but have since started growing right back over the dead areas.
Same colony after the swing.. it's since come back very nicely.
No name LFS coral, but has a lot of potential... Anyone on an ID?
Aussie Sarmentosa, finally beginning to branch out

bland A. Plana from LFS that has since gotten a lime green interior, blue coralites and a red body... This one is finally beginning to branch.
