178 hours with no power part II---the cleanup.

Just having the power back is a relief on all fronts. That pump coming on was beautiful.
But it's not over til it's over, and the tank came out with a lot of issues.
I let it warm gradually, with the heater, until it was 79.
But warmth means decay, and I had missing fish under the rockwork, dead ones.
The cold also killed off all my bristleworms and probably some of the crabs. This, when you have dead to dispose of, is a scary situation.
I finally had light enough to read the water tests. Salinity was bang on.
I'd dosed Prime about 3-4 times during the depth of the disaster, and it squelches nitrate-to-ammonia goings-on, but I'm not sure whether it converts the ammonia or whether it actually binds the nitrate. At any rate, a functional tank can't go on leaning on that product. I had to let it do its thing, and just watch the readings.
Water changes are definitely in order. I had, ice cold, about 20 gallons of salt water left from changes I'd been doing.
Alkalinity is 9.
Temperature is 80.1.
Salinity 1.024.
Nitrate tested at 50. This is not good for corals or fish. It's all sps coral, so it's hardy, but---that needs to come down to 2 or lower.
Haven't tested the phosphate yet, or the calcium. It's on kalk, so I'm not too worried about calcium. But I will test those when I get the nitrate hammered down.
There are 3 methods of lowering nitrate: nitrate remover beads, polyfilter, vinegar dosing (on a schedule), and water changes. I applied all of them, starting with the 20 gallons I had in reserve. I am now making up new saltwater.

Survivors are: the golden domino damsel, the black and white 3-stripe (both dascyllus species), and ironically, one chromis. Dascyllus and chromis hate each other. I found that out after adding the chromis. But here we are, all on the same liferaft...so to speak.
Snails, mostly limpets, maybe some strombus grazers---survived. Crabs are few, but my oldest and largest, a hermit with striped legs, is alive. He can be undertaker to the demised, and thank goodness. [edit: now spotted about 7 of the strombus grazers, and another of the larger hermits.]
And my live rock and half the cheato moss, so it will have released some phosphate.
Survivors include every single aiptasia and asterina.

Losses: my bristleworms, probably the breeding mysis shrimp colony, various fishes not named above.

But the tank is alive, and the fish are starting, with the water change, to act more comfortably, and the contracted corals are expanding. My lights are Radion Pro, so I just started them up on 'acclimate,' which puts my preset program on a daily increasing level, starting at 25%, to let it ride at 50%, where it was before the disaster. [edit: the freshwater tank lost only the 2 angels: catfish, tetras, pleco, Aussie rainbow, all came out fine.]

We're clearing the water. I've got new salt water perking for a series of water changes---I'll remove 5-10 gallons from the sump and put new water in. It's a 105 gallon system with 30 gallon sump, so if I just keep this up daily, no muss, no fuss, because I never even have to stop the pump or worry about warming the water at that relatively low dose, it'll do fine.

I also am resuming vinegar dosing, which is a nitrate reducer. It's useful for an old tank, or a tank that's had dieoff, as this has had, and certainly do not do this without a need, and without a copy of the tables used for the amounts you should use for what size tank and when. But between that dosing, and a PolyFilter pad, a bag of Purigen, and water changes, plus a filter sock (which I don't routinely use, but am doing so now to assure water clarity)---plus the water changes, we will be in much better shape. I won't add any fish or corals until the tank is completely stable and the nitrates are way, way, way now from where they are. I'll just continue nitrate abatement procedures as long as it takes, which may go to another 32 gallon barrel of salt water besides the current one.
 
Sk8r - you're teaching well. Keep it up.

ps. Glad you pulled through the storm. I had it less bad than you (dramatically less bad).
 
The fact that your system is not entirely wasted is testament to your commitment and skill in this hobby, Sk8r. Thanks for documenting your progress!
 
We had an act of desperation today---our former second-largest crab attacked the largest to get his shell, there being nothing else left, and (grimly) likely the demised fish provided them a growth spurt. Not a shell to be had else. So what do I do, crazy me, but drive to Petco to get the last hermit shells they had, 3 of them, and put it in---get a turkey baster, sip up some water and shoot into the shell as you drop it in and it will sink instead of floating about for 6 weeks.

Well, crab loser had lost both claws and was really wretched, crawling about with no shell that would fit him, trying to survive in the rocks, so I landed the shells near him. He'll molt, producing new claws, if he can survive long enough. Meanwhile I'll try to see food lands near him.

Outside of that, two successes: first, chromis #1 ate, and chromis #2 showed up to eat. And both dascyllus ate. This turns an important corner. If fish are without food for TOO long they can lose the food trigger and go ahead to starve to death. Generally they can last two weeks without eating, but adding the cold stress, I wasn't sure. I couldn't even get interest out of the chromis, and the b&w dascyllus acted as if he might be eating ground krill, but I couldn't prove it. Now I have four surviving fish, all eating.

I had to do something for that poor crab. Anything that fights that hard to live deserves some help. Hoping he finds one of those shells.
 
Damn that is bad news for sure, but at least not all is lost, nice guide you setting in case some one goes thru the same deal
 
Saddest thing was losing them one by one, as the stress just got too much for that particular species. The incident started at 4 pm on Tuesday. If we'd gotten power by Friday I could have saved far more of the fish. As it went on, I just had to stay the course, keep dosing what I dosed, and hoping I'd just save the cycling in the tank and keep the tank itself live. That I was able to save four fish---a second chromis popped up for food today---and that they're now eating---I'm real happy with that. I don't expect any more survivors from the rockwork---I sort of hoped for the gramma, but I think he's gone. Sigh. Losing the watchman pair was saddest, because they were my oldest, from a previous tank. But I did what I could.
 
I mentioned that all the corals survived. Hammer, frog, candycane and acan. I had just this last month or so gone on LED. I set it for 25% when power came back, with a slow increase, about 5% a day, and of course the nitrate level is particularly hard on the candy cane---so it doesn't need any more stress. The slow light restoration is a real plus to these lights. It's an option they have. Getting the nitrate down as fast as I can will help. Corals aren't that fragile: they demand light of the right kind and they don't like phosphate or nitrate, but give them their basics and they're tougher than you'd ever think.
 
Sk8r,

Are you using the (optional) reeflink to do the acclimation, or is there a way with the lights alone? Just curious...

Thanks for documenting this process, helpful and interesting to lots of us.

It's a Radion Pro unit, a single one---I have a deep wedge tank and one is enough. I connected my laptop to the unit's USB port, brought up the program, and there was this nice little 'acclimation button.' I clicked it, it gave me a blank to set the starting percentage of light, I picked 25%, and it did it next time it turned on. Every day the lighting ramps up another notch, and the corals are doing fine.
 
He has not, though the bandit took the largest new one and left the contested shell behind beside the old urchin skeleton in which the loser-crab has taken refuge, plus the other two new shells. The loser-crab is hiding in the urchin-skull, which is really a great place for him---having no claws, he needs to eat somehow, and that upturned hole does collect detritus, so if he can stay safe in there that's best. He has been out to examine his old shell just outside, but lacking claws, he can't turn it to get inside. Still, there's no crab but the pirate that's large enough to use that shell, so I figure either the pirate will go on using the new big shell, or reclaim the old one, in which case he will leave the new big shell behind and it will all work out. It's even possible he may come back and turn the old shell, then leave in the big new one again, (indecision plagues hermits this way) leaving the old one in a better position for the loser-crab to reclaim.
 
They're tough little buggers, it should pull through. Might not be able to rip apart larger bits of meat, on it's own, without the large claws. The next time you're in a dollar store or craft store, check for the bags of mixed shells. There are usually lots of good snail shells for the hermits in them.
 
And loser-crab has gotten his old shell back. The pirate did exactly what I thought he would can came back to finger the discard, which flipped it so clawless can get into it again.
 
I'm still fighting the nitrates, but I think it's getting time to put in the replacement fishes, considering that the tank boss is a fairly large damsel with notions of world domination. She doesn't bite but she has a particular place she wants everyone to be and works hard to keep them in those niches. Before she's sure she rules the world, I need to get a collection of newcomers to keep her quite busy.
