Multiple fish deaths in just hours...help

So my girlfriend and I have a 29 gallon tank, we had gotten rid of our rainbow shark and loach 2 weeks ago due to swimming space. Things have been fine... I don't live in the same
State so I hadn't seen the tank for 2 weeks and last night I get a phone call saying all our tetras are dead (10) along with 3 of
Our cories. All that is left is her angel fish and a albino Cory and
A
Dwarf gourami... We tested the water and it was fine... However she told me that the night before she had noticed a reddish/whitish fuzz on our fake silk (sigh) plants (she has a hand of death when it comes to real plants) and on some other decorations... It doesn't seem to be on the driftwood... Atleast not from what I can see.. And it's not on the Anubias leaves or it's rock its rooted too... It was free floating in the water... And upon removing the filters (one at a time) to rinse them during a wc I saw a lotttt of this "fuzz/gunk" in the assembly of
Our HOB filters.. Not moving
Just sitting in the bottom like it was sucked up and couldn't be passed through
The filter.. I don't know what could have killed the fish... The other. Cory looks awful.. And the angel seems to breather
Extremely extremely hard under the water every ten minutes
Or so... Then goes back to normal.. And the gourami isn't as active as he was... I don't know if the fuzz killed
Them.. Or what... But something's goin on...

On another note the carpet cleaning company came
To her apart yesterday when she was at class.. Which is when she came
Home and
Saw 1 dead tetra got rid of it teste water and
Went to work.. And came home to the mass casualty situation...
She said she read that even if your aquariums on a stand somehow the carpet cleaning
Stuff can be passed airborne into your water or filter and
It is extremely toxic to fish.. So you need to cover your open
Cut outs with a towel, which she didnt... I dont think this is what happened but some of the dead fish were white, which means lack of oxygen? Or do all fish turn white 2 hours
After dying.

We have a 29 gallon tank with a small 100gph
Power head(tetras loved swimming at it and messing around in the flow) and a fluval c3 and an aqueon cheapo secondary filter... Both HOB.

What a mess, and I'm sorry for your loss of fish. What specifically your water parameters, and I hope you're not using the strips, but liquid test kit :) I'd give more info, than they are "okay".

I doubt it's the fake plant, unless it's not aquarium safe. Sounds like you may have ammonia levels. Re check your water. The fuzz stuff sounds strange. It's possible something went in the tank from the carpet company, I'd call them, and see what they do as a procedure in cleaning. Do a big water change. If you can get a cheap air pump put that in, to get more oxygen in the tank. Are you using Prime as a water conditioner? That will help you in an emergency detox any high nitrates or nitrites you may have. Remember nitrates should be under 20ppm

Best of luck

The carpet cleaning could definitely be a suspect...especially if they sprayed freshener or carpet protector. If you add an air stone, be sure to open the windows and air the place out first. Otherwise, you could be pumping the contaminant directly into the water. As always, a major water change can do nothing but help. Good luck.

I too am sorry for the loss of your fish.

Most carpet cleaning is done using extraction with a nonsudsing detergent. I doubt that this impacted the fish.

The reddish fuzz may be cyanobacteria which can be caused by high nitrates and/or phosphates. I'm also suspicious about other water params like ammonia and nitrites.
What was/is your water change routine (volume and frequency)?

If there's reason to believe the water was somehow contaminated, you may need a total tear down. Otherwise, I'm thinking you need to do a couple of 50% water changes with a good conditioner like Prime.

As usual, Dad has some great advice. Having been in the business, I would not ignore the carpet cleaning altogether. There are many things besides extraction that can go on during carpet cleaning. Some carpet cleaning doesn't even involve the conventional extraction. What Dad suggests is good advice in any event. To play it safe, I would cover any tanks before having carpet cleaning or any other commercial cleaning or exterminating service done and turn off any air pumps going to the aquarium.

My water test results (master test kit) are 0 ammonia 0 nitrite and nitrate is I between 0 and 5. My conditioner
Is prime. We perform water changes every week now. When it was
Cycling we performed them almost everyday to keep the levels safe, now it's weekly.. But I performed one yesterday because I rinsed my filter media out in some dirty water and although
Probably unadvisable ... I had to rinse the filter casings out and intake tubes since that fuzz was everywhere. Today I am going to do another water change so I can try to clean up te rest of it.. It's only on the fake stuff... Driftwood and Anubia are not affected... Our remaining fish seem a little more active today aside from the angel which leads me to
Believe it wasn't a carpet chemical... The way I see it if it was toxic enough to kill multiple species of fish in mass quantity the other 4 wouldn't have lived and be living still...

I just hope these little guys pull through.

Just to update I saw more fuzz after doing the test this morning... And I'm not about to have my fish get even worse.. I checked the filters as the water was cloudy last night and they were gunk free today. So I decided I'd pull all the plants (silk) out and all the rocks and decor... So I got them all out because this fuzz has to go and being so heavily planted I can see and move the substrate better to clean it... After doing this I was inspecting the "fuzz" what it looks like to me is our tropical flakes broken down into smaller pieces with white fuzz around it... Maybe just the natural decaying process. Since our loach and Cory's have moved our sand all over I decided to even it
Out and move it so it's once again higher in the back and there was so much food coming out... It was insane...

I asked my girlfriend to feed the fish because I had a suspicion she was madly over feeding.. She gave a hugeeee pinch for just the few we have left and upon asking how much she had given the 15 we once had she said a lot more.. She also informed me today that ammonia has been extremely high the past week so she's done water changes everyday tryin to get it down... I didn't know this...

Could these fish have died from massive ammonia exposure and finally just finished them off all at once? The fish seem happier now and ate super active.. I did a 20 gallon water change because I couldn't get all the old food and stuff out until on my 4th bucket..

Maybe this fuzz on everything was algae as we never have gotten an algae bloom in 2 1/2 months and the red/white fuzz seems to be food cover in a ball of white fuzz... I've never seen food being broken down so maybe someone can advise me what this seems like..

Over feeding = ammonia. Ammonia = dead fish.. And the old food is being broken down and that's why it's covered in this white fuzz/goop?

I talked to her about this because although I've told her and shown her how much to feed she said they always were going at it when she fed them so she'd give them more... Sigh.

The best of intentions sometimes produces the worst of results.
It does sound like she was overfeeding and this could have lead to an ammonia spike if not for the fact that your testing suggests otherwise.? It would seem now that the 'fuzz' may be a fungus - just another normal 'creature' in dealing with organic waste. Although not often seen in more mature tanks.
As you well know, we need to feed in moderation so as not to foul the tank. Moving forward, lower stock levels will also help.

Granted my test suggested that it was not ammonia... However I wasn't here when they died , she did two water changes before I got home the next day and I tested it when I got there in the AM, so her water changes may have lowered the ammonia levels.. Doing a 60% water change and all.. Either way our levels are normal now.. I told her to wait it out and make sure the fish do okay and to work on not over feeding and in a month we can see about adding a few fish.

I would not tend to expect deadly ammonia levels from overfeeding. The Nitrosomonas bacteria only require 9 hours to multiply by binary division, and the Nitrospira up to 20 hours, and this should have handled the ammonia if any from overfeeding. There are other issues with overfeeding of course, so it is not safe regardless.

The coincidence of so many deaths with the carpet cleaning cannot be ignored. I would never clean carpets in a room with a fish tank. You have to be very careful as any chemical substance will get into the air, and straight into the water. Even painting is risky, some paints more than others. And window cleaners are bad.
