Question: Are these water conditions hurting my axies?

And I thought we were so close to solving the problem. :sad: This was definitely a strange, weird issue, and I'm sure there was something useful to have learned if we'd figured it out.

Best of wishes. :happy:

This is really odd, it must have been the tank itself?
The fact that you re-homed them speaks of you love for these animals, anyone who wants the best for them would do the same in this situation. Letting go of these animals is something not everyone would be willing to do, even if it is the best for the axies, so it obviously shows your dedication to their care. Nice to see :happy:

I thought we were close to a solution also. And thanks for everyone's help. I learned a lot from the forums over the past year. I'll always remember the entire year I had with my precious little ones. It was amazing to watch them grown from tiny 3 inch juvies to huge 9.5 inch adults. I hope I can get them a really good home and hopefully they can go together. I'm putting them in the For Sale section of this forum since it's way better than any other site and everyone here as a basic knowledge.

I'm so fortunate to have been introduced to axies. I have lots of video footage and photos to cheer me up for the sad days when I miss them.

This tank may have been contaminated with polypropylene, which can leach quaternary ammonium biocides.

Can you explain that in little, short, words that a mere mathematician can understand?

How is a tank likely to get contaminated by polypropylene?

Are quaternary ammonium biocides dangerous, or do they just cause false positives?

If this is the cause for this case, what could have been done about it?

This instance was very puzzling, since the cause seemed to be narrowed down to the tank itself.

polypropylene is a commonly used plastic. the tank may have been contaminated with it in any number of ways, like a piece of plastic finding it's way into the oven during tempering, or a mistake when mixing the sealant.
quaternary ammonium compounds, or Quats, are used in commercial kitchens for dish and tool sensitization. To humans, it's far less toxic than chlorine in the levels needed to kill bacteria or viruses, but even small amounts in your tank will hamper and crash your cycle again and again. long term exposure may eventually cause nerve damage if there's enough in there. 4ppm probably won't hurt your critters, But that tank may never be able to support a healthy colony of microbes. The manufacturer should be contacted. there may have even been a recall already.
