I hate my tap water. Sometimes, the tap water is yellowish, sometimes it is crystal clear but with foul smells. I had lost fishes due to this. That was years ago. Not anymore since using this Diamond Water filter :-

See how dirty is this ceramic cartridge (left side) after using it for only 4 days. See the difference (right side) after the ceramic filter cartridge cleaned.
I do a simple chlorine test on the direct tap water and filtered water.
You can see (left side) that the chlorine test gives somewhat yellow color to indicate quite a lot chlorine present in my tap water. Using filtered water (right side), non-detectable chlorine present, the filtered water is crystal clear.
In short since using this water filter , I have reduced my fish lost. No need for water conditioner (anti chlorine) either. And absolutely good for human consumption too. I feels more healthy now! as my fish are too
Not promoting, just want to share. Can use other brand of water filter. Like to attack problems at the source, that is all.
Best Regards
