I misdosed prime when doing a 50% water change the other day (1/4-1/2 dose). I had a brain fart on the liters versus gallons. I'm concerned that I may have done this several times as my partner has been in the middle of a high-risk pregnancy and I have been distracted (over now). on the other hand, due to (preemptive/paranoid, it is a relatively new tank and I knew I was going to be gone for long periods of the day and that dosing would not hurt them so I just went ahead) concerns about ammonia I had been dosing pretty heavily before that so I don't know if it could've built up and compensated? However, it has been four or five days and I do not see signs of illness. I did add an aerating filter, but they do not seem to be flocking to it or otherwise showing signs of distress. At this point, can I stop worrying? I was away (at NICU) so it was not added between 11/21 and today just now, but I'm watching them on the camera and they are fine.

Is it possible that they sustained some kind of minor damage that isn't immediately apparent? Cumulative damage that isn't apparent? I did feel like they were at the surface a little more than usual on one of the days in between then, but they haven't been doing it since I added the extra air (which was a coincidence, I just found my old air cylinder maybe 12 hours later) and it was only that one day. I am not going to take it out to test whether they seem to get worse without it. I did have a fish one time that had an illness such that he was current swimming against the filter and I know what it looks like, that is not happening. That day that I felt like they were at the surface an unusual amount as according to the fish camera took place about a day after when I say they have been fine I mean, they have been very lively and in great spirits, eating well, probably the best I've ever seen them honestly and not in a twitchy scary way.

Water parameters are testing normal, but I did not do an oxygen test.

Additionally, I live in a converted warehouse and chlorine testing my sink is actually showing zero, I don't know if the strips are wrong or I'm reading them wrong. I'm ordering a dropper test. I didn't actually realize we were not getting residential water until now and will be doing water changes with distilled water from now on in case of contaminants. These are young fish by the way, under one year.

I am so mad at myself, I can't believe with all the anxiety I have about this and even OCD that I would let something like this happen. Please go easy on me, I have really bad anxiety to the point that I have sui ideated about being afraid that I hurt my fish before (yes I am in treatment. No, I am not in danger, I am just saying I take it seriously). My partners pregnancy and postpartum nicu period is over and so I am no longer distracted (he is a solo parent, we do not live together, this is not my baby) and I definitely will never let this happen again.
