Seems the system is just over a year old as I started to add livestock the first week of December 2014. It's had some ups and downs and some errors on my part have contributed to the downs which resulted in the loss of corals along the way, but I'm pretty happy how things are progressing at this point.
Some changes that have been made during the last year are in lighting, a change of skimmer and supplementation. I had been using 2 part for most of this past year, but a few months ago I switched to kalkwasser and am happy I did. The tank is dosed each hour via a GHL dosing pump. This seems to have helped stabilize PH a bit. There are no real lows during the night - the range over a 24hr period is 8.15 to 8.35. I think that's pretty reasonable. Prior to switching, the PH would drop to 8 and sometimes below.
I also switched to dosing VSV vs just vinegar, and based on testing and appearances, this is working out much better. PO4 is near the undetectable range using a Hanna ULR and NO3 is pretty stable at 1 - 2 ppm. I'm not at all unhappy with that. Though there's still room for improvement, the corals have colored up reasonably well.
Most of the corals are mariculture. I know there's some who do not believe these to be viable, but so far I'm having pretty good success with them. I also have a few that were fragged from RC member tanks and they're doing fine too.
Over the past few days, including earlier today, I was busy mounting the many corals that I neglectfully left sitting on the sand bed or perched on rocks. Not a good idea at all. A few have been damaged from falling over, falling onto another coral or were buried in sand, causing the loss of polyps and flesh. Not a good thing. So the last few days were well spent rearranging things and getting my coral house in order.
Here's a video of how things look today. Some of the LPS don't appear happy, but they're doing fine. I probably should have waited longer and allowed them to open up before shooting the video, but well ............

Oh I just wanted to add, I'm really happy with the health of the fish. They're all plump and looking very colorful. An, knock on wood, there have been no losses

I'm looking to add a few wrasses, since they're lacking in presence in my tank.
