Hi All,
I don't use any De-chlor either, but I do use an HMA filter cartridge (actual name Pentek CBR2-10, removes chlorine and heavy metals), I also use RO (but that's a discus thing

).
IMO, Modern water companies, quite often mix & match from differing areas, dependant upon season, rainfall and 'ground-works' hence the water (particuarly Chlorine & Chloramines) can vary dramaticaly (don't trust the 6month avergae web-site tests!!).
Chlorine will de-gas over-night (with an added air-stone), but chloramines will not!
Check here for which is best for you!

Better-safe than sorry, Cheers, Mick B
