Hi, sorry for the very late reply.
I am currently very busy since I am moving to a new home. Tank has been very busy as well, as I am segregating which corals to keep and which to let go. I have a new tank on its way and I am soon making my new rockscape.
I am still deciding which fishes to keep and which to let go. While I love all my fish, I am tempted to try other varieties.
Some unanswered questions:
1. I am using a Sony A7 camera with Zeiss 55mm prime lens.
2. The only things you will see in my sump is a biopellet reactor and a ReefOctopus XP2000 skimmer. I hope I remember to take a picture of my sump and post it here - it is really ugly though so keep your expectations at a minimum haha. That's part of the reason why I am excited for the new tank build.
3. I do not have any experience with dying acans.. if the skin is peeling off maybe your alkalinity is out of place?
4. I am currently not dosing anything, but I have been given an AquaVitro FUEL by some friends which I dose when I remember to (about once every 3 weeks?). I am usually not home, especially at the moment wherein I am very busy - which is why I haven't had the time to gaze at my tank for a long time.
