New to this forum, so forgive any misstep 
...but not to tanks and such - I have a degree in Marine Zoology, and have been reefing since the late 90's. My current tank is a 90gal Oceanic (so sad they are not sold anymore, I'd love to get a larger one), with Radions and Vortech, UV, chiller, etc...I also keep 4 crinoids, some as old as 18 months, one 6 months, and 2 new that are doing well. I would guess it is a pretty typical SPS setup. My corals generally are doing well with the exception of a recent echinata dead that has me puzzled, but I'll hunt for a replacement in a couple months. I like to let things sit after something dies. If anyone knows about crinoids, you will know that my ability to keep them means I have a very stable tank.
The real craziness of late has been almost all my fish died from what I can best see as velvet in the course of a week. I blame no one but myself as I let my UV get dirty and in haste didn't quarantine my recent fish. Bad Nathan...they all died very quickly in the span of a couple days - and nothing I did saved them - all the same thing: looked fine, then a little logy, then rapid breathing and dead. One I tried to dip, died, as I read it is generally too late. The first couple of them were the newest, so I assumed stress, then the old guard died. All but 2 clowns.
So, I am leaving the tank fish free for a while to let the cycles break, with one exception: my 2 clowns show no effect...I read that this is possible as health fish might develop immunity to velvet. Again, pouring over everything I can find I am wondering, do these seemingly immune fish also need to be removed? If they are immune does that mean that the parasite is not attaching to them vs. that it has no effect? I have been unable to determine this from the literature I have read. Because obviously, I do not want to add more fish back in to the tank in 2 months if there is a chance this will happen again. I have upgraded my UV to a 25 Watt from an 18 Watt to better match the load of a 90 gal, and from what I can read, there is nothing else much I can do except set back up my QT tank for any new fishes.
Thoughts appreciated.
Also, just putting this out there, I have been slowly adding in sensors to my arduino tank monitor, temp, floats, etc...if there is anyone else out there who would love to talk arduino, let me know!
