Discus and all fish dead

I am asking around to get others opinions. I had an unexplained die off in my tank. All died except the leeches. I did a WC and treated the water just like usual. A few hours later the leech which I hardly see were free swimming like crazy. Then the discus and sids were gasping at the top for air. I did another WC well everything died, well almost everything the leeches are still free-swimming, some did die. I have never had just plants. I wonder if I should just throw everything away and bleach everything. Not sure how long for the next batch of eggs are due to be born. Should I soak the plants in PP or just get new ones. This is so pissy
I really miss my mated pair of discus. They may have been deformed and bad color they would never been breed. I will have to ask to see if anyone wants to share some culls.

75g, pair of gold rams , ABN, 1 adult 2 young discus, 2oto's, 6ADF's, 3 anglefish. 96w 6700k-light 6hrs raised, No C02, Excel, EI dry macro's and micro's, Eheim 2126, 18w UV, 2 Nano 270 powerhead. wall of bubbles for more O2 for such a deep tank.

What did you treat with? How big was the WC? Were the temperatures stable? Was it tap water or RO/RODI?

Maybe a little of 50% Everything was the same. I tested after and the tank read 0,0,4+-
The only thing I could think of was the water company added something. This happen about 2hrs after the WC and they went very quickly. Nothing could have fallen into the tank nor can I see that I contaminated anything. What do I do with the plants?
while I got the fish out I was doing another 50% WC

How many plants do you have in there and how much are they worth?

Deaths that quick were, like you said, probably caused by something added to the water, in which case, it's probably not going to "stick" to the plants if you give them a thorough washing with nice clean water.

Try a PP soak to get rid of the leech eggs.

very sorry to hear about your loss

your case might be different, but this thread about my tank might be one of the reasons, in my case, it was mixing hot water during water changes - thereby depleting oxygen content of water, as soon as i stopped using hot water the problem was gone

That was my first thought when I read your post. Why not contact the water company and find out if they have added any new additives. You need to rule this out as part of trouble shooting to find out what caused it, otherwise if it is the cause, you are screwed everytime you do a water change and nothing else you do will make any difference.

I will call P.U.D and get report. Maybe they have an answer. Most of the plants are not worth much except the fissiden On wood I have had for 3 yrs. I wonder if I could put it in the PP and then just put it in some water for awhile to see if I get leeches. The rest I guess I will toss. I am going to need to read up on planted tank without fish to see how that works. I think it would need cycled also.
Thanks for the kind words I just needed to voice this mess.

Hang on a sec, wasn't this from just yesterday? https://www.plantedtank.net/forums/783752-post9.html
I read about your poor fishies last night, it sounds like the meds may be responsible, IMHO. Sorry for your loss.

If it wasn't the meds you treated in the other thread, I'd suspect the water co.

The only time I've had a large die off is when the water co. did some major line cleaning and added a lot of chemicals in the process one time years ago.

Sorry to hear of the fish loss btw.

I had something similar happen to me a few weeks ago. I am just now getting the tank back up. Here is what I posted elsewhere. Now that I am reading this forum, I think the heated water was the culprit. I used water warmed to 84F for my Discus:

"Trying to solve a mystery. I have a 75 FW tank that has been setup for over 2 months. I have had all my community fish in there for around 2 months. I recently decided to order some Discus, SAE, and some more cardinals for the tank. The shipment came on Thursday. The fish were placed into the tank and each bag was acclimated slowly.

*I did not have a quarintine tank setup at the time because the Discus were essentially the fish I was worried about and wanted them in the main tank. Anything from this point on would have been quarintined.*

The Discus were stressed and appeared to be loosing their slime coat so I added more Prime to the tank and also some aquarium salt. The salt I added was a fairly small amount compared to a normal treatment (1/4cup vs 1 cup). I used less due to plants in the tank but I felt the need to help the slimecoat on the Discus mildly. A few cardinals died that night but I chaulked it up to stresses of shipping. I decided to do a 33% water change to be safe.

However, the next day 16 of my 20 cardinal tetras were dead as was 1 Discus! They remaining 4 were at the top breathing heavy like they had ammonia poisoning, but the test kits showed 0 for ammonia and nitrite. I turned down my CO2 which was not pumping out that many bubbles per second to begin with. I removed the 4 remaining cardinals and put them in a bucket with fresh tap water (Primed) and immediately they looked better. This led me to believe that it is definately a chemical poisoning the fish in my tank, not a disease and the cardinals are just the most sensitive.

Could the salt cause some reverse osmotic conditions in a particular plant to release something toxic to fish? I do not own any exotic plants just your standard LFS types. The only other thing I could think of was that 2 days prior to my receiving the shipment of Discus I decided to clean my tank (50% water change) and move some plants around. I had an anubis nana that was covered in spot algae and some hair algae. I removed it from the tank and one end smelled rotten. I cut that end and dipped the leaves in a mixture of H202 and water for ~1hr. I rinsed it with water and placed it back in my tank. Since the incedent, I have removed this plant...just in case it was leeching something into the water.

I did a 25% water change after seeing the cardinals breathing up top, and another 50% change the next day after finding most of them dead. The 4 I moved to the bucket are all doing fine. The other fish were starting to look stressed, hiding, ocassionally breathing at the top...etc. They would look normal for awhile, eat and then go hide. I decided to break down the 75g tank and moved everything to freshly setup 20g tank. I moved a few plants over, and one of my filters.

24hrs later they all look normal. Colors are bright, they are swimming normally and even the 2 surviving Discus are starting to eat. WTF happend to my 75g?! Here are my guesses:

1.) H2O2 plant reaction w/ or without help from aquarium salt (reverse osmosis).
2.) Some fungus remaining on driftwood became toxic...at just the right time...not buying that, but throwing out the driftwood since fungus has not settle even after 2 months.
3.) Something toxic on the outside of the fish bags that were placed in the tank to acclimate. I never even thought of rinsing off the outside the bags before putting them in my tank. Or from the newspapers they were packed in, heat packs...etc.
4.) CO2 even though I trimmed it and aerated with various water changes? I did switch from having the CO2 on 24hr on a pH meter so it would turn itself off once it got to 6.2 to having a timer added so that it was off ~10hrs at night about a week ago. CO2 just does not seem likely especially with multiple water changes.

Any thoughts, ideas, comments, or other insight would be appreciated. I am using this forum as my therapy session. From now on all bags will be rinsed and fish put into a Q tank. Lesson learned but mystery not solved!"

All this could have been due to the temperature of the tap?!

Also are you sure you have leeches and not planaria? Planaria often pop up in tanks where people tend to overfeed....Discus tanks.

Mystery solved: I am the one at fault. Now my husband will work with me on my tank.

I need to explain. I am a cancer patient and I use my tank to hold me together. My husband watches me like a hawk. I forget what I am doing or now I forget what I did.
He said that I added a first does of fluke tabs, after the water change. So I blame the fluke tabs and water companies increased PH. My husband is helping me set my tank back up. The fluke tabs killed some of the leeches and then I got mad and poured bleach in. So I am just starting to cycle today. He used a micro hot shot to vac the gavel many times. Got about a cup Leeches (dead). The plants we soaked a couple of hours in PP. They look a little limpy but they may survive. I got an used filter sponge from a friend to speed things along.
Have to wait to get things cycled.
I will want Discus back.
I will try to be more careful on what I post. Don't want to confuse anyone else

You bleached your fish??? God, what a horrible death! Sorry for your losses, I hope you will soon have some good new ones.

Can't be any worse then the way they died with no O2. But no I did not bleach the fish.
Everything died in my tank before I started killing off the leeches.

I hope your treatments are going well for you and am glad your tank is helping. Hopefully your tank will be up and running very soon.
