leaving water to stand to remove chlorine?

Hi Zoo - I meant should I use 'tap water conditioner' which treats chlorine and chloramine, as opposed to 'prime' or so something which does chlorine, chloramine and the resulting ammonia.

Anyway - I treated a bucket of tapwater with 'tap water conditioner' and then tested for ammonia (I didn't know how quick the conditioner works, so I tested immediately, an hour later, and 5 hours later). No detectable ammonia. So that answers my question, I can steer clear of the ones that do ammonia (I prefer to add the least ammount of chemicals necesary)
 
oh... yeah, as you found out, it should be fine. Any resulting ammonia will be negligable and easily removed w/ water changes. I used API "tap water conditioner" for a long time, have had trouble finding it lately though.
