Hey, Woman! I am so sorry, Kym! Good wishes your way for all the wet pets and hoping you find out what went down.

Once ~ I forgot to turn back on everything, after a wc with the discus ~ woke up at 2AM and all are lying on the tank bottom and my favorite was spinning around! It was horrible. He died, but I did an ER wc and they all popped up ~ Actually posted on SD during the whole crisis.

I cried the whole time. You go ahead and cry. We can swear here? I will swear for you!

AK- how deep is the substrate? it could have been the release of gases if its over 1.5 inches... if its deep mix it up a bit while removing the next batch of water that should help a lot. (be sure the fish are not in there BTW) another option is to look for missing members of the community or anything that could be leaching (dead plants, drift wood etc)
just trying to think out loud here and see if any of this helps at all

I am hardly an expert on any of this and while some of those items may be toxic it almost as if it seems the oxygen may be low. Even though your adding fresh tap water and while your readings may be high. They are not extreme enough to kill fish that quickly. I really do think the oxygen content of the water your using may be low if they are "gasping" for air. I have had tanks with elivated levels of all 3 of those items higher than you mentioned and never lost fish.

I could be wrong however just adding my 2 cents ;) Hope things get worked out for ya!

I'm officially gutted. I woke up at 7am only to see the same thing happening all over again. Dennisons jumping so hard they were hitting the top of the hood, trying to escape. So far, three dead Dennisons and one (of only two females) dead Discrossus Filamentosus.
After a 2am 60% water change I have another nitrite spike. I agree with Curt, I have had elevated levels for nitrite and never lost a fish before. Gasping for air = no oxygen.
So, at 7am I do another 60% water change, it takes the nitrite level from .50 ppm to .25 ppm. I lowered the water level so water coming from spray bar is like a water fall. I added an airstone to the other side of the tank and a massive wall of bubbles is coming from that side. What else can I do??

At 7am I called Ron (my LFS guru and friend) and woke him from a sound sleep. I tell him what's happening and he asks if I can move the fish into my other tank (Discus tank). I tell him that if I do that it'll be tough to then catch them later to put them back in this tank. He says, "Better than the way you are removing them now, which is dead". Good point. I was only able to net out five Dennisons and one Columbian tetra. They are sitting in a bucket, filled with "Discus" tank water. Discus tank is 84 degrees, community tank is 78. Do I add them to the Discus tank or put them back in their tank, which so far, everyone in that tank is now comfortable, pecking the substrate for food. (They will not be getting any)
Should I add the five Dennisons and one tetra back to the tank, or put them in my 10gl QT tank for now?

Trying to work backwards. On Jan 3rd I did a water change, replacing the foam blocks in the Fluval. They were disgusting, like sludge, and couldn't get them rinsed in tank water, they were that dirty.

On Jan 10th, basic water change, 50%.
On Jan 18th, basic water change, 50%.
On Jan 25th, basis water change, 50%, with new nozzle, and also added three handfuls of additional Eco-complete, to fill a "hole" that was left after I repositioned a Tiger Lotus and sword, who needed to "switch" spots, due to light/growth pattern.

Tank has Eco-complete substrate, varying depths, 1" in some spots, 3" in other areas.

were it me..i would float and add them to the Discus tank for the simple fact that its running well and will have the room your fish need.
also would take a net handle and poke around your substrate (pay particular attention to deep spots) and see if any bubbles get released if they do mix up the substrate a lit to get all of it out.....
lowering the level to get the water fall effect is a good idea. are you ok with it like this long tern? if not then perhaps the addition of a powerhead (with or with out the venturi feature) would be helpful for surface agitation....

i doubt your nozzel has anything to do with the current issues.....

as i am not familiure with eco-complete i will let other chime in here.... curriius however was there any cloudiness to the tank over the last 24-48 hours? i am wondering if an algae bloom could have sucked out so much oxygen?

No cloudiness at all, will go poke around the substrate now. Long term I'd never be able to sleep in my bedroom again for all the noise the tank is now making. It sounds like Niagra Falls in my room right now. Not familiar with a powerhead. Bummer is that it's a planted tank and all that surface agitation will not make the plants happy, but the fish are first and foremost. I am so bummed out right now.

Bear: info on Eco:
Eco-Complete description:

ok a few things here the bio balance to help the cycle faster is bacteria.. next is this looks like something that could have an expiration date on it.. does it? is it expired? was it stored safely with no way anyone or anything could have tainted it? next

power heads are used to create motion in the tank and if directed at the surface will create a wavelike motion that assists with gas exchange...now as for the plants being unhappy they are from water and water moves in nature so in time they will grow stronger and deal with it....

The Eco was stored safely, I do not see an expiration date (bag is only a month old) and I even added additional handfuls of this to my Discus tank a few weeks back, with no problem.

I will look into getting a powerhead. This tank houses loaches and barbs, all who prefer lots of water movement. Screw the plants.

Also wanted to add one more pic. These are of the nitrite testing. Left, tap water reading, middle-taken before water change, right-taken after 60% water change. The furthest right is my nitrate reading, which is slight, but measurable. Just trying to put everything out there in case somewhere a cause comes to mind for my troubles. Is this amount of a spike enough to cause such trouble for my fish, or are we still thinking oxygen depletion???
