That would absolutely suck if it's with the water company... I wouldnt be able to purchase a filtration system like that...

Depending on your needs, these system came a long way in affordability since the first time I looked at them.
My water tests came out with "Quaternary Ammonium Compounds" QAC. Very toxic to "Life in general" in quantities that are unbelievable. Ok it's not there all the time...
But it comes and goes. And without a battery of tests every time, you get scared of the next water change.
There is no regulation as to any kind of safe levels would be. But in the last months my tanks been hit 2 times and it's the sole thing that was different (in all the tests I have)
It refers to a group of chemicals with a specific molecular structure that makes them useful for various applications. they consist of a central nitrogen atom with four attached hydrocarbon groups and a single positive charge. This structure gives them unique properties. Due to their structure.
QACs are cationic surfactants. This means they have a positive charge, making them attracted to negatively charged surfaces like dirt and grease. Additionally, they are amphiphilic, meaning they have both water-soluble and fat-soluble regions. This allows them to interact with both water and oil-based substances.
These properties make QACs valuable for several purposes:
Their ability to bind dirt and grease in water makes them effective cleaning agents.
Some QACs can disrupt the membranes of bacteria and viruses, killing them and acting as disinfectants.
They can also be used as preservatives in some products due to their antimicrobial properties.
QACs are widely used in various products. Disinfectants, Cleaning solutions, Fabric softeners, Personal care products.
It's important to note that while QACs are generally considered safe for most applications when used according to instructions, there can be some potential downsides. Improper use or prolonged exposure may cause skin irritation.
Their persistence in the environment is a concern, and research on their long-term effects is ongoing.
As an experienced Aquarist... At some point you know that it's not "you" the problem, or at least not directly.
It doesn't mean that you are ongoing the same thing, But in your interior, if you feel that you know that you're doing everything right...
In case of fish that dies unexpectedly... It's nearly always the water that is the problem.
