Well, I'm at my wits end, maybe someone can come up with some ideas.

Moved everything into the 125, no losses. Everyone settled in fairly quickly. Needed to upgrade my sump, as the Eshoppes R100 is only about 15g, and the new skimmer wasn't going to fit in it. DIY'd a 55 into a sump, now I'm right at 30-32g with enough room for my skimmer and biopellet reactor. This was about 2 months ago.

Finally got the time, and took the system down one night and gutted the old sump. Installed the new sump and replumbed. Put all the equipment in and fired it back up. All in all, everything was down for about 2 hours. Topped off the sump with water that I had mixed the night before.

Got home from work the next day and everyone was unhappy. Frogspawns, hammers, acans, and favias were all drawn in. Acros and montis were browning up. Only the Zoas didn't seem to mind.

Tested water and nitrates were off the scale of my Red Sea kit. Used my API kit and they were between 40 and 80. Did an emergency water change with the 15g I had on hand and mixed another 25g. Did the 25g the next night. Went to the Critter and bought 25g more Saturday, and 25g again last night. (Ordered new filters for my RODI, in case that was the problem, and they needed changed anyway.) As of last night, nitrates were still above the 4ppm on the Red Sea kit, but not showing at all on the API kit.

So far, I've lost 5 acros with the rest either browned and STN'ing or bleaching. My monti's are all browned and white showing on all the edges. The frogspawns and hammers have "some" tentacles showing, but they are not extended much past their skeletons. The acans and favias are shrunken, but don't look to be receding. The zoas and palys are still blissfully unaware anything has happened.

I did the rest of the parameters testing and this is what I've found:

SG: 1.025 (I use Reef Crystals)
Temp: 76.7 (Lower than I like, going to upgrade my heaters) (I run two heaters, never just one.)
pH: 8
Amm: 0 (hate testing this, but with everything dying off, I had to check)
Nitrate: >4 (RSP)
Phos: .07 (Hanna)
Ca: off the scale on my Red Sea Pro kit
Alk: 7.5 (RSP)
Mag: off the scale on my Red Sea Pro kit

I'm starting to dose Alk to get closer to a balance with Ca. I've started Vodka dosing to handle the excess nitrate issue. I have purchased the parts to build an ATS, just working out the design and placement.

Does anyone have any ideas as to what might have happened, or possibly what direction to move? I've been focused on the nitrate issue, but as of last night, I'm also going to put some time into getting the other parameters corrected (or at least within reason, I don't like to chase "perfect numbers.")

Thanks for any thoughts you might have.

I need to find my multi meter and check that. Thanks, Ryan, that's one I hadn't thought of.
 
so the big change was down for 2 hours, swapped sumps, modified plumbing, added new salt water to make up for difference in sump volumes?

you used all existing equipment or just the new skimmer?

how long had sump been built? any chance silicone wasn't cured?

was it a new or used 55 gallon tank?

assuming new skimmer was cleaned prior to use?

just rambling through some questions

are you running carbon?
 
Jay, first paragraph all correct.
All existing equipment, had to order pump for new skimmer, still waiting on it.
Thought about the silicone as well, but it sat for about a month and a half after baffles put in.
New 55, vinegar bathed for 2 days before baffles put in.
Just put some Chemi-Pure Blue in this weekend in case there's something in the water I can't test for, but before that, I've never run carbon on thus system (90 or 125)
 
When I switched tanks, I shook the rocks pretty good to clean them out (no dipping or anything) but could there have been enough junk in there that could have caused enough of a nitrate spike to cause this "crash"? Maybe the nitrate trail is a dead end, don't know for sure.
 
Just trying to help here and throw out ideas..
So you moved to a new tank? What did you do with the sand bed? Everything was running fine in the new 125. So I'm guessing the problem doesn't lie there.

As said earlier you added a sump and alot of new water.

Sump - What kind of silicone was used for the sump? It wasn't silicone with mildew killing additives was it?
New Water - when was your refractometer last calibrated?

Your mag and cal are off the charts maybe it got exacerbated with the addition of fresh salt water? I'm not sure though that would have caused the quick reaction your corals are having though.
 
I looked this morning, and it appears that the 100% Silicone that I used DOES have the mold/mildew inhibitors. Going to take the sump offline tonight, put the little sump back in, and try to do enough water changes to get any contamination out. May not be the real problem, but I'm already out about $1000 in corals, so at this point, I need to do whatever I can to save what's left.
 
Can you run some carbon in a reactor or at least put some in a media bag.
 
Picked up some carbon today, gonna' start running that. Pulled the new sump this evening, and put the old little sump back in. Luckily, I still have the 90 sitting around, so I'll use it to make up a major water change, thinking something in the 60-75 gallon range. I guess while I'm working on rebuilding the big sump, I'll work on getting my water parameters back in line.

Hopefully, I'll start to see some of the critters showing signs of relief.

Dang man! I hate seeing this.

I have always been ultra paranoid about what silicone to use when DIYing a sump. I always would just use the big silicone tube they sell at the critter that is made by some Tank manufacturer. (cant remember who) even though it cost more than the stuff you can get at Lowes, at least I knew it was safe.

I almost guarantee that is/was the issue.
 
A very short time after removing the sump and bringing the carbon on line, the hammers and frogspawns started coming out, albeit just a little. There's hope for them yet. The acans and favias should swell back up pretty quickly. The sticks are gone, and the montis are pretty much toast. Fish have all been fine the whole time, maybe the vodka just made them not care much what was happening!
 
Thanks, John. It'll be a while before I work on the sump. Gonna concentrate on seeing what I can salvage in the tank first.
 
mac.. Gosh.. UGH. I HATE reading this. I would definately say the silicone was your issue. I always make sure I get the RTV silicone when building anything tank related. I either order the specific aquarium stuff or get some of the black we have at the office here. its reef safe RTV fortunately.
 
Sucks hearing that but at least you figured out what the problem is. I was thinking that maybe taking the biopellets offline for two hours might have killed some of the bacteria on them. I always leave those pellets tumbling even if everything else is off.

I concur with buying the more expensive silicon made by a tank manufacturer for the peace of mind.

Good luck getting everything straightened out.
