Change in water parameters due to haze?

[apek19]

Hi fellow hobbyists, I was wondering whether there could be a change in water parameters/content due to the haze.

I did a 20% water change in one of my tanks last night and found my beloved angel pairs dead when I came back from work just now. I did the usual de-chlorinating regime using seachem prime. So far this has been my weekly routine and rarely differ my process. I traced back my steps and I couldn't find a reason they could be dead. Has anyone else experienced this?

Another point to note is that my block is undergoing re-roofing works. Could either reasons be the cause?

Hope to gain some enlightenment from the experienced members here

Is your tank open top? Did the noise from the re-roofting process stress the fish out?

Yes, it's an open top. Do you think the haze might have affected the water parameters? Anyway, I don't think the noise from the re-roofing is that loud to affect the fishes. I stay on the second floor. Hmm, still remains a mystery. Thanks for asking!
