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)
